30GT Flotronic Air-Cooled Reciprocating
Liquid Chiller Features
Carrier's 30GT air-cooled reciprocating
chillers offer peak operating performance in nominal sizes ranging
from 15 tons to 400 tons (53 to 1400 kW). Sizes up to 35 tons
offer thermostatic expansion valves (TXV) while sizes 36 tons
(127 kW) and larger offer either standard TXV controls or Carrier's
patented Flotronic long-stroke expansion valve (EXV) controls.
With over 25,000 long-stroke EXV Flotronic chillers installed
worldwide, Carrier's 30GT chillers are favored by specifiers and
customers. The
powerful 30GT Flotronic chillers incorporate the latest in integrated
microprocessor control and refrigeration cycle optimization devices.
The electronic expansion valve (EXV) and the microprocessor controller
allow the chiller to operate at low pressure differentials, and
accurately control refrigerant superheat during start-up and load
changes. The result is efficient energy usage and accurate
leaving-fluid temperature (LWT) (to 1.25 F [0.7 C] from the LWT
set point) functions. These chillers offer cost saving advantages
because they are smaller and easier to install as well as exceptionally
efficient. Full and part load EERs (Energy Efficiency Ratios)
are up to 10.4 for full load and 12.0 for part load resulting
in a significant savings in operating expense.
