Heat exchangers

Plate Heat Exchangers

The plate heat exchanger is constructed of rectangular corrugated aluminum Plates, arranged to form passages between them. Alternate passages carry hot medium and cold medium. The direction of flow in two adjacent passages is at right angle to each other.

The framework is also be constructed of aluminum or epoxy coated aluminum, a face and bypass damper can be added on the plate heat exchanger upon request. A condensate drain pan, which made of galvanized steel, galvanized steel electrostatically powder coated with an epoxy-polyester coating of thickness 60 μ or with stainless steel SS304 or SS316 can be supplied upon request.

Rotary Heat Exchangers

The rotary heat exchanger consists of a thermal wheel that rotates at slow speed and transfers heat from the fresh air to exhaust air during cooling cycle and from exhaust air to the fresh air during heat cycle. The thermal wheel foils are made of aluminum and available in 5 different options Aluminum, epoxy coated aluminum for sensible heat transfer and Aluminum hygroscopic chemically treated, Aluminum absorption type is an enthalpy transferring material of high quality.

The material consists of an aluminum core with a silica gel based coating or molecular sieve based coating that has a high moisture transfer capability for sensible and latent heat transfer, where the effectiveness reach up to 80% for sensible and latent heat. The drive unit consists of a geared electric motor and chain drive with provision for chain tensioning. One side of the casing will be provided with a removable access panel, for withdrawal of the wheel and the maintenance of the motor.

 Run Around Coils

The run around system provided by Klimallco consists of a coil in the hot air stream and another coil in the cold air stream.

These coils will be connected together through a piping system and a pump will be used to circulate the heat transfer medium water with a percentage of glycol.
