With green refrigeration fast becoming a commercial reality, companies such as SWEP are taking the opportunity to meet niche needs with new product ranges.

SWEP, a global specialiser in brazed plate heat exchangers, has released a new range of brazed plate heat exchangers for high-pressure CO2 cooling applications - specifically designed to meet green refrigeration demands.

Stefano Bellado, Segment Manager of Refrigeration at SWEP is responsible for the launch of the new range and commented, “The use of CO2 as a refrigerant is changing status from being a ‘green alternative’ into becoming a strong, commercial solution. SWEP is proud to introduce an environmentally friendly range of products that provide both energy savings, reliability and lowered footprint.”

The new range consists of seven products, all tested and approved for the extreme pressure conditions that are characteristic of trans-critical and cascade operations, which are often used in commercial refrigeration systems such as supermarkets.

The series includes a U-class, for applications operating up to 140 bar at 135°C, a D-class for applications operating at 60 bar up to 100°C, and the E-class for sub-critical applications operating at 56 bar up to 100°C.

The CO2 product range includes the B16DW, B17 and B9, which are suitable for use as a gas coolers, evaporators, economisers and oil coolers in CO2 trans-critical applications. The 120TH and 400H are made for use as evaporators and condenser in cascade operations, as are the 12H and 25H, which can also be used as suction gas heat exchangers.

According to Bellado, SWEP plans to further expand its CO2 portfolio, the Segment Manager explained that a forward looking strategy was hoped to meet, “the growing market needs for eco-friendly refrigerants.”
