UK:  Fujitsu has introduced a range of factory engineered electronic expansion valves (EEVs) and a control unit as a DX kit, to enable other manufacturers’ air handling units (AHUs) and fan coil units (FCUs) to be incorporated into a Fujitsu VRF air conditioning system, or be connected to a dedicated Fujitsu VRF outdoor unit as a one to one system, to heat or cool outside air for building ventilation.

The three EEVs in the range – UTP-VX30A, 60A and 90A – support a wide range of capacities and a variety of control options, with temperature being closely regulated by multiple sensors located in the AHU or FCU.

Connectable capacity ranges from 5kW up to 50kW, with two EEV units connected in parallel on larger 33kW, 40kW & 45kW systems.

Control of the DX kit/AHU system can be either from a Fujitsu VRF system, a central controller or an external BMS system.

To train engineers on the new units, Fujitsu has set up a working DX kit system in its training facility at Elstree, and added a DX kit course to its training programme. DX kits can also be selected via the Fujitsu Design Simulator software program which also has a dedicated training course available.

Says Fujitsu product and specification manager Colin Goode: “We believe these new kits will prove very popular with contractors and specifiers alike, as they expand the application of our VRF systems enormously and add flexibility to the system design process as a whole.”
