Product Data EVERGREEN® 30HXA,HXC076-271 Condenserless and Water-Cooled Liquid Chillers with COMFORTLINK™ Controls 50/60 Hz 75 to 265 Nominal Tons (264 to 931 kW) Water-cooled and condenserless chillers designed from the ground up to meet the needs of today and tomorrow: • Unit fits through a standard door with no disassembly required • Chlorine-free HFC-134a refrigerant • Dual independent refrigerant circuits • Smooth compression using twin screw compressors • AHRI certified IPLV efficiencies to 0.51 kW/ton Alarm Status Service Test Temperatures Pressures Setpoints Inputs Outputs Configuration Time Clock Operating Modes Alarms Quality design and construction make the 30HXC (water-cooled) and 30HXA (condenserless) units the preferred chillers. Easy installation The 30HX chiller has a compact design that fits through a standard door opening and requires minimal indoor space. The 30HX chiller is delivered as a complete package for easy installation. There are no extra controls, clocks, starters, or other items to install. The 30HX unit also provides a single location electrical power entrance (using the accessory field-installed control power transformer) and quick, easy piping (using victaulic-type clampon couplings). The 30HX 208/230-v, 230-v, 460-v and 575-v 60 Hz units are designed in accordance with UL (Underwriters Laboratory, U.S.A.) and UL, Canada (Underwriters Laboratory, Canada) standards to minimize electrical inspection time.

Features/Benefits (cont) A quick start-up is assured once installation is complete, since each 30HX unit is manufactured at an ISO (International Organization for Standardization) 9001:2000 listed manufacturing facility to guarantee quality. In addition, all 30HXC units are tested under load at the factory to provide reliable start-up. NOTE: The 30HXC units shipped with optional nitrogen charge are tested for proper operation of the electrical components but are not run-tested at the factory. Easy operation The 30HX units have a quiet, lowvibration design featuring screw compressors....
