FEKS conventional products are used for cooling and heating in HVAC; cooling and heating in industrial processes; oil coolers; evaporators, condensers and economizers in the refrigeration industry; and economizers in air-source heat pump water heaters. When applied to phase change heat transfer (evaporator, condenser and economizer) or strict requirements for pressure drop, FEKS conventional products can get higher heat transfer efficiency

FEKS E12 E22 are mainly used in the economizer for the refrigeration system.

FS12、FS14 and FS-Y12 mainly used in the second-level heat exchanger for the Wall-hung stove, is a Wall-hung stove manufacturer custom products with high heat transfer efficiency and long service life.

FEKS BHE for Air Dryers is a product customized for refrigeration dryer industry with high heat exchange
efficiency and long service life.
Different with other brazed plate heat exchanger using for drying compressed air, FEKS BHE for Air Dryers combines heat recovery, evaporator, and moisture separator of the compressed air into one modular (also named “three-in-one” modular) and it possesses certain unique features as below:
①. The number of plates in the separator can be determined by its working load, which is the volume of the compressed air. With no need independent air compression design, the product cost is minimized.
②. The addition of pre-drainage at the heat recovery can lower the power consumption of the evaporator.
③. The connection at the top of the moisture separator can provide part of the cooled dry compressed air to the user, or be used for regular cleaning of the product.
④. The evaporator adopts the asymmetrical runner design (when there is REF phase-change heat transfer) , so as to improve the efficiency of heat exchange and lower the pressure drop of the compressed air.
⑤. Special structural reinforcement design is adopted locally to withstand high temperature change and long cycles of fatigue testing.

FEKS Y series heat exchanger main purpose is to cool the auxiliary water, secondary flue gas. Compact structure, save energy, reduce maintenance, but will cause the system to get higher water consumption, flue gas dust concentration cannot exceed 30mg/m³.

FEKS dual-circuit heat exchanger are mainly used in evaporators and condensers in chillers and heat pumps, and applicable to some HFC , HFO refrigerants. The dual-circuit design is better than the back-to-back solution, and it has full performance in both full load and half load conditions.
