Refrigerated Circulators - Grant LTD series
Compact circulators with stainless reservoir tank and integral
refrigeration unit utilising ozone-friendly R134A refrigerant.
Immersed parts are manufactured from stainless steel and Ryton
fire-retardant plastic, with nickel-plated copper cooling coil.
The control unit has a liquid crystal display, desired
temperature being set by pushing in the control knob and turning
until the required temperature is displayed. When the knob is
released the actual bath temperature is displayed. Low liquid
level protection and adjustable high and low temperature
protection devices are fitted.
Circulators are supplied complete with a flat stainless steel
lid with plastic handle.

Recirculating chillers
RC chillers deliver a flow of controlled -temperature liquid,
providing powerful, regulated cooling for many types of scientific
apparatus.
Circulator
- A source of refrigerated, temperature controlled liquid, to remove heat from, and control the temperature of, other apparatus
- For circulation through open and closed systems
10 to 60°C operation
- RC350G,RC400G and RC1400G control the liquid temperature by using a
heater to balance the effect of the cooling power, they can also be
used as heated circulators to raise and control the temperature of
external equipment up to 60°C
- RC3000G controls temperature using a hot gas bypass system, which is
effectively an on-off control for the refrigeration system; this is
highly energy efficient, but means that the RC3000G can not be used
for heating; the most stable performance is achieved when cooling a
large volume with a stable heat load
- RC350G:-5 to 60°C
- RC400G,RC1400G,RC3000G:-10 to 60°C
Stability to+ -0.25°C
- RC350G,RC400G,RC1400G:+-25°C (10L system volume)
- RC3000G:+-0.5°C (25L system volume)
Digital setting and display
- Ensure accuracy and reproducibility of set temperature
- Constant display of actual liquid temperature for at-a-glance assurance that the equipment is functioning correctly
Cooling power @ 20°C: 325W, 375W, 1100W, 2800W
- Choice of four models for you to select the cooling power appropriate
for your application
- Powerful cooling for high heat extraction and
rapid cool down
- Ozone-friendly refrigerant
Construction
- Each model consists of a temperature control unit, small reservoir,
refrigeration unit and circulating pump, all housed in an outer case,
with control panel and digital displays on the front, and inlet and
outlet pipes protruding from the rear, for connection to the external
system
