High-efficiency water chillers

Aermec’s NRL range includes air-cooled water chillers, heat pumps and condensing units. They have high-efficiency scroll compressors to achieve high EERs and are designed to use R410A. 18 sizes offer cooling capacities from 53 to 469 kW and heating from 58 to 510 kW.

Features include a high-efficiency direct-expansion stainless-steel plate evaporator with an anti-freeze electric heater. Fan cycling maintains head pressures during low ambient conditions.

A heat-pump version can product hot water up to 55°C. There is a free-cooling version to reduce energy consumption when ambient temperature falls below the return-water temperature.

Optional features include electronic expansion versions for improved energy efficiency with changing loads and partial or total heat-recovery options.
