UK:  Hampshire-based Advanced Engineering’s EasyFind now has a new formula making it easier for refrigeration and air conditioning engineers to detect the smallest of leaks.

The EasyFind Bubble Up Leak Detection Spray’s new and ingenious formula now makes it much simpler and faster for service engineers to pinpoint both large and small leaks when sprayed onto joints, pipes and line components offering a more pronounced and visual “bubble up effect” when it comes into contact with refrigerant leaks.

With the new F-Gas Regulation requiring regular mandatory leak checks and stronger penalties for operators who fail to comply, coupled with rising refrigerant prices of between 20-30 per cent already this year, leaks are set to have an increasing financial burden to equipment owners.

The convenient EasyFind spray can be described as ‘it does what is says on the tin,’ safe, reliable, economical and quick, requires no preparation or equipment, and is suitable for all refrigeration and air conditioning systems.

UK:  Foodservice refrigeration specialist, Adande, has teamed up with ice cream equipment manufacturer, Carpigiani, to offer a range of dedicated dessert workstations. Designed as complete solutions for the preparation, production, storage and plating of professional artisan gelato product, the units are suitable for restaurants, hotels, fine dining, delicatessen and ice cream parlours. With a compact footprint of just 1100 mm width by 700 mm depth, the dessert stations are ideal for kitchens with limited floor space.

The workstations are available in a variety of configurations to meet desired capacity, including a layout which has Carpigiani units mounted on an Adande two drawer refrigerator. The worktop of the Adande unit can also accommodate additional equipment, such as a whipped cream machine.

Base mix ingredients are heated in the Boil 5 before the liquid is transferred to the Labo 8 12 E, where flavouring is added and the mix is stirred and chilled to – 8oC. The artisan gelato is then transferred into pans for pull down to the suitable storage temperature in the Adande® unit. For high volume operations, a pre-prepared UHT gelato mix may be poured directly into the Labo 8 12 E.

The ability to set precise and accurate temperatures in the Adande drawers has particular advantages for holding premium gelato. The bottom drawer of the Adande unit may be set at – 18oC, which is the optimum temperature for the longer term storage of gelato, eliminating the formation of ice crystals. The upper drawer may be set at – 14oC, during service, which is the perfect temperature for soft scoop service.

Alternatively, the lower drawer may be set at – 14oC for holding gelato during service, with the upper drawer set at + 4oC for the storage of complementary ingredients, such as fruit, toppings and sauces. The top drawer, at + 4oC, may also be used for chilling dessert plates and sundae glasses.

The Adande units are castor mounted, allowing them to be moved easily for cleaning regimes. The drawers and the gelato equipment each operate on a 13 Amp power supply and with no plumbing or water supply required installation is simple.

Carpigiani has recently opened a development kitchen at which chefs and ice cream operators can gain first hand experience of the dessert workstations. Appointments for demonstrations at the Carpigiani facility are available upon request.

Scott Duncan, Sales Director, Carpigiani, stated:

“Artisan gelato is a premium product, which requires holding at optimum storage and service temperatures. The unique technology of the Adande drawers helps maintain the gelato at the correct temperature, eliminating the formation of ice crystals for perfect product quality.”

Karl Hodgson, Sales Director, Adande, added:

 “Carpigian’s position as a world market leader is helping us to introduce the Adande® brand to new market sectors in the UK and on an international level.”

UK:  J&E Hall’s new ambient beer cooler can cut energy bills for cellar cooling by up to 40 per cent. The unit uses free cooling to allow beers to be stored at a perfect temperature during the winter months. When the outside temperature is low enough, the fan-operated cooler brings cold air into a beer cellar to reduce the temperature and will switch off the main refrigeration cellar cooler system while it draws cold air from outside – cutting energy bills and saving money.

J&E Hall Product Sales Manager Tony Twine said: “It is estimated that up to a quarter of a pub’s energy bill can be accounted for by its refrigeration requirements – so publicans and breweries are always looking for a more cost effective way to cool their beer cellars.

“The J&E Hall ambient beer cooler can save a large proportion of energy costs over a year – up to 40 per cent. The key to this is the use of free cooling, cold air from outside, a ‘greener’ way of cooling beers. The J & E Hall ambient beer cooler also contains no refrigerants. This helps reduce servicing costs and extends the life of the main cellar cooling system.

“The J&E Hall ambient beer cooler is easy to install and also fits with any make or model of main refrigerated cellar cooling system on the market.”

The ambient beer cooler operates when it’s cold outside at temperatures under 8°C. When temperatures rise above this level the ambient beer cooler will turn itself off and revert back to the main refrigerated cellar cooling system.

The J&E Hall ambient beer cooler is fitted to an internal cellar wall and connected to the outside via a rigid 150mm circular duct. It is then electrically connected to the mains supply and the refrigeration cellar cooling system.

The J&E Hall ambient beer cooler has simple keyhole fixings. It is supplied with:

  • fresh air entry duct
  • ambient air temperature sensor
  • cellar temperature sensor
  • washable air filter
  • 2m mains lead
  • instruction manual.

“The beer cooler’s green credentials speak for themselves,” added Mr Twine. “It’s a plug and play product which will make a significant impact on energy bills for pubs, clubs, restaurants and breweries.”

UK:  Mitsubishi Electric has launched the next generation of its award winning Ecodan air source heat pump range, with a host of new developments, one of which is the use of a plate heat exchanger in a domestic cylinder and patented Scale-Stop technology to remove the risk of limescale build-up.

The launch comes as the Domestic Renewable Heat Incentive (RHI) moves from its legacy stage into supporting new market growth, with the company developing the advanced range is response to the growing need for renewable heating in the UK.

Ecodan was the first inverter-driven air source heat pump in the UK to receive MCS (Micro Certification Scheme) certification and the first UK-manufactured unit to receive the prestigious Eco Label.  It is also the only air source heat pump that have received the Noise Abatement Society’s ‘Quiet Mark’ and the first to offer intelligent room sensing as standard.

Mitsubishi Electric has invested heavily in R&D facilities at its UK manufacturing plant in Livingston to focus on the experience of the homeowner, simplifying installation and maintenance, and making monitoring even easier:

Mitsubishi Electric reshapes air source heat pump market

The next generation – the FTC5 range, which is available from January 2015, includes a complete new range of cylinders which focus on improvements in heat loss performance; hot water recovery efficiency and time; and ease of installation and use.

All ten of the new cylinders dispense with the traditional internal coil method of water heating and instead use an external plate heat exchanger which increases hot water heat up efficiency by 17 per cent over previous models.

The FTC5 range offers three different options for homeowners:

  • The standard level which is pre-installed at the factory, offering remote energy monitoring using partial estimation of energy use;
  • Level Two which includes the addition of an electric meter; and
  • Level Three which adds a Metering and Monitoring Service Package (MMSP) heat meter, enabling homeowners to receive an additional RHI payment of £230 per year for seven years..

Plate heat exchangers use forced convection to heat the water cylinder, rather than the natural convection of a coil and this increases the Delta T, meaning that the water heats up more quickly and recovers temperature quicker when some hot water is used.

Other initiatives included in the launch include:

  • A patented cold inlet diffuser for all of the Pre-plumbed cylinders, which ensures reduced mixing of cold inlet water with stratified hot water.
  • A new titanium immersion heater which sets a new standard for operational life, even in the hardest or most aggressive water conditions. 

“We expect the heat pump market to continue to grow steadily through a combination of the RHI and in answer to the increasing costs of oil and LPG”, explains John Kellett, General Manager of the company’s heating systems. “We have prepared this new range to ensure that Ecodan is ready to answer that growing need”.

Founded in 1921, Mitsubishi Electric is a global, market leading, environmental technologies manufacturer, producing an advanced range of heating, air conditioning and ventilation equipment. The company realises that ensuring the right solutions are selected for each individual building, requires collaboration by all involved. Mitsubishi Electric has therefore changed the way it does business to ensure engagement with all involved in delivering sustainable buildings so that together, we can make a world of difference.

INTERNATIONAL:  Alfa Laval has introduced a new compact DM shell-and-tube heat exchanger – the first refrigeration product in this family that has been specially developed for sub-zero temperatires.

The Alfa Laval DM is more compact in size thanks to a new design based on a single-pass dry expansion evaporator instead of the previous two passes, making it more convenient to install in places where space is a constraint. The DM guarantees maximum efficiency at minimum costs, which results in a higher level of competitiveness for applications.

Alfa Laval has developed the DM shell-and-tube heat exchanger with a unique patented refrigerant distribution system in line with the latest European regulations on low GWP refrigerants, optimizing it for R407F and R134a refrigerants, yet maintaining its compatibility with R404a and R507.

The DM shell-and-tube is ideal for supermarket or industrial process cooling as these applications typically demand evaporation temperatures in the range of -10 to -20°C depending on the system efficiency and brines such as propylene and ethylene glycols.

Metal baffles with an advanced design help to improve the brine side performance in the DM shell-and-tube model. Exchange tubes with an inner groove pattern also maximize the heat transfer coefficient and limit the negative effects of pressure drop.

What’s impressive about the DM shell-and-tube heat exchanger is that despite its smaller size, it boasts a significant improvement in performance of at least 15 percent in comparison with the previous model, resulting in a more cost-efficient investment for Alfa Laval’s customers.

“All in all, it is a more compact unit with better performance that gives the customers great value for money,” says Piergiorgio Barbato, Business Manager Shell & Tube.

The first installation of the DM shell-and-tube heat exchanger in Europe is now operational. This new heat exchanger is available for order worldwide.

Alfa Laval is a leading global provider of specialized products and engineering solutions based on its key technologies of heat transfer, separation and fluid handling.

The company’s equipment, systems and services are dedicated to assisting customers in optimizing the performance of their processes. The solutions help them to heat, cool, separate and transport products in industries that produce food and beverages, chemicals and petrochemicals, pharmaceuticals, starch, sugar and ethanol.

UK:  BITZER Advanced Header Technology (BAHT) for tandem and trio Orbit scroll compressors makes it easier to use these products in parallel circuits for air conditioning and heat pump systems. The newly developed suction gas header with integrated oil distribution plays a key role, specifically directing oil to one of the compressors in the tandem and trio units. The system even works when uneven compressors are combined and allows the frequency of a single compressor to be adjusted.

The benefit of BAHT is that only one suction line is required for many compressor combinations. The system functions with consistent reliability at high and low suction gas volume flows and promotes uneven capacity adjustment through different displacements and compressor housing sizes in one unit. Another benefit is that active oil management with an oil separator is no longer necessary for distributing the oil. Even when a compressor is shut off, oil distribution is maintained in the unit.

BITZER’s ORBIT 6 scroll compressor range comprises five models with cooling capacities between 27 and 51 kW. They are ideal for air conditioning systems and heat pumps, featuring low sound levels. The larger ORBIT 8 series has six displacement volumes between 29 and 77 m3/h with 15 to 40 hp outputs. The sound level is about three dB(A) lower than that of conventional compressors. The very low oil carry over rate of less than one per cent improves heat transfer properties and increases system efficiency and reliability.
