Dimplex study reveals air curtain cost saving

Dimplex is conducting a study on the running-cost savings offered by its air curtains, in conjunction with the Carbon Trust.

An initial study shows that using air curtains can save up to 33 per cent of HVAC running costs by keeping treated air inside and separate from the external environment.

The study takes typical commercial environments, both heated and air conditioned, and looks at how the energy performance changes when air curtains are added to protect doorways, compared to an open door with no protection.

Both scenarios show that the efficiency and cost of air treatment improves when air curtains are used.

Used in conjunction with heating, Dimplex air curtains mean fewer heaters need to be installed, as warmed air is retained in the premises for longer.

The capital cost of the air curtain is offset in part by this saving, with the remaining investment recouped from savings made on running costs.

In an air-conditioned environment, a reduced loading means an upfront saving on equipment capital expenditure.

Dimplex's air curtains are suitable for doorways up to 6m high and, as the range is modular, multiple units can be linked together for coverage of wider doorways.

Dimplex air curtains can be used in de-rated or interlocked installation mode and thermostat regulation is standard to give up to 97 per cent savings on air-curtain running costs.

The units also feature a Building Energy Management System (BEMS) interface to give maximum control, including a timed automatic switchdown mode for optimum energy savings when used with a compatible magnetic door sensor or PIR detector.
