SUCTION LINE HEAT EXCHANGER
On certain medium low temperature refrigeration systems, the use of a suction line heat exchanger can be recommended in order increase efficiency by transferring heat from the liquid feeding the expansion valve to the vapour going to the compressor, thus increasing the refrigerating effect at the evaporator inlet (by subcooling the liquid coming from the condenser). Another advantage is the suction line heat exchanger is to prevent liquid droplets from entering the compressor, where it can severely damage the pistons and other internal components. The exchanger will protect the compressor by vaporizing the droplets that might be present in the suction line.
PLATE & FRAME HEAT EXCHANGERS
Gasketed plate and frame heat exchangers have the advantage of offering a small footprint and a flexible design, while still being very efficient in heat transfers. These advantages make the plate and frame heat exchanger a perfect choice for a wide range of applications. Thanks to their excellent heat-transfer coefficients and their slim design. Docal’s gasketed plate heat exchangers have established themselves as an alternative to shell and tube heat exchangers in many fields. Docal reasserts its expertise as a manufacturer with the ITEX range, the result of long years of technical and thermal development during which nothing was left at random.
