R32 air-cooled chiller

R32 air-cooled chiller

Kaltra extends the portfolio of low-GWP chillers with the launch of Lightstream Scroll range based on its Versa platform and operating on refrigerant R32. Lineup's capacity ranges from 300 to 1100kW at nominal conditions and demonstrates the same high level of efficiency as previously introduced R452b-based models.
Lightstream Scroll R32 available with the same extensive set of hydronic options, free cooling circuit, safety options, low-noise models, and control software functionality as found in existing Lightstream Scroll chillers running on refrigerants R410a and R452b.
Lightstream Scroll R32 chiller series is setting new standards in energy efficiency in full- and part-load operation. Thanks to the latest scroll compressors, highly efficient microchannel condenser coils, and advanced control algorithms, new chillers achieve a particularly high level of efficiency at loads of 35 to 100 percent.
In combination with high energy efficiency, Lightstream Scroll chillers running on refrigerant R32 with GWP value as low as 675 (one-third of R410a GWP value) significantly minimize the global warming impact.
R32 (difluoromethane) is a mildly flammable, A2L-class, zero ODP (ozone depleting potential) refrigerant with excellent heat transfer and pressure drop performance - both in condensation and vaporization, and a substitute for R410a in new equipment. R32 exhibits heat transfer coefficients higher than those of R410a, thus far primarily used in small-to-medium and residential air conditioning units.

Hybrid dry coolers: a water-saving cooling solution
Closed-loop process cooling systems are gaining attention among a growing number of industries with the introduction of more stringent regulations on water use and increasing costs for water purchase and discharge. A hybrid cooling system where the dry cooling and evaporative cooling technologies are taken together is an attractive alternative to open-loop cooling towers in terms of both water saving and efficiency. The basic operating principle of the hybrid dry
