We can supply three types of Air to Air Heat Exchangers:
Air to Air Plate Heat Exchangers, or Air Plates as they are also known, are an extremely effective and low-cost way of reducing the heating or cooling loads on the treatment of process air and air conditioning systems.
A reduced heating or cooling load means lower energy bills and carbon emissions.
Air Plates use the exhaust air to pre-heat or pre-cool the incoming supply air, without the two air streams ever mixing. The box-like construction of the heat exchanger is supplied with flanges that can be drilled through for connecting to adjacent ductwork or are suitable to be slid into an enclosure.
Energy recovery can be as high as 85%, depending upon operating conditions.
Corrugated plate surface types, for high efficiency and energy recovery.
Smooth surface plate types that can be easily cleaned for dirty air streams.
Cross-flow models for good efficiency (typical 50-60%) and low pressure drops.
Counter-flow type for high efficiency (typical 75-85%).
Aluminium - non-corrosive air streams - max 200c.
Epoxy coated aluminium - adds protection to the aluminium for air streams containing salts / chlorine.
Stainless steel - for ultimate corrosion protection - max 230c.
Thermal Wheels are installed across hot and cold air ducts. As the Thermal Wheel rotates, the extended surface is heated by the hot air stream. When the rotation passes through the cold air duct, the wheel cools down, thereby transferring heat.
The following sizes are available:
(a) Stainless Steel Plate Type Exchangers - Uninsulated
(b) Stainless Steel Plate Type Exchangers - Insulated
(c) Tubular Air to Air Exchangers
Counterflow Air-to-Air Plate Heatexchangers
The typical operating range for the counterflow plate heatexchanger (CPH) is where the ordinary crossflow plate heatexchanger would not bring sufficient efficiency - or become ridiculous large - and the rotating heatexchanger would either be too expensive, not airtight enough and/or not achieve targeted temperature exchange.
The PCF exchanger is a metal counterflow plate heatexchanger that is manufactured in a high spec. aluminum allowing a dry efficiency easily exceeding >80% under ordinary conditions - and >90% calculated under conditions with enhanced condensation.
Ordinary air volumes for not exceeding 150 Pa pressure drop in a single pass exchanger with a width of 1600mm ranges up to 5000 m3/h (~1.400 l/s). However, you may easily double or triple this (or more) by making multi pass arrangements or just by extending the width of the unit or allowing higher pressure drops.
Do note, that when coming up in larger air volumes you will reach a breaking point where you may consider the rotating heatexchanger as the more economical choice, compared at similar pressure drops.
