SWEP launched a complete high-efficiency product range for chiller applications. This includes a full range of high-performance evaporators and condensers that are also climate-friendly.
SWEP offers a wide range of BPHE sizes with different plate geometry and different distribution devices to suit the various chiller applications and the technology allows the pressure drop on the secondary side to be reduced while maintaining good heat transfer. In SWEP BPHEs (for example, a dedicated R410A evaporator for the 14 to 140 USRT cooling capacity range), the technology reduces the hold-up volume of the inner circuit by 30 percent. This lowers the charge of R410A, saving money on refrigerant and helping manufacturers comply with environmental legislation. Furthermore, the refrigerant channels are narrower, which increases heat transfer and hence efficiency. On the secondary side, the pressure drop is lower (by some 30 percent compared with normal chiller cases). This means less load on the secondary fluid pump and an improved COP.
SWEP offers a variety of products for chiller application:
- The DFX310 and the DFX400 are effective, versatile True Dual flexible chillers and climate control applications. Their advantage is their ability to offer full performance at full and half load. They are optimized for extreme performance with the refrigerant R410A.
- The B3 enables efficient heat exchange in applications with small flows and extreme demands for compactness. Easy to install and use, the product is small yet flexible, which allows it to be used for economizer applications and small water coolers.
- The B30L is optimal as a suction gas heat exchanger. The main objectives are to minimize gas side pressure drop and to restrict the superheating of the gas to 18 to 36 degrees Fahrenheit. This will guarantee the efficiency and reduce the wear of the compressor.
