Chiller for open circuit (air cooling)
Coolnit

CL-80R
Product Code:0031810-000

Standard open circuit chillers for lab. Precise temperature control type.



Use optional port tank for circulation to scientific instrument such as rotary evaporator (sealed circuit circulation).

Main Application

Circulation to culture device such as jar fermenter
Circulation to analysis device such as spectrophotometer and HPLC
Cooling of rotary evaporator (for sealed circuit)

Features

For open circuit machine use for circulate mainly to water bath

Circulation system for open circuit is used mainly for preparing constant temperature chamber. It is optimum for control temperature of sample.

Various output and external sensor can be used

Output thermograph and cutout operation signal and use of external thermo sensor (sold separately) are available. Programmed control is available by connecting program setting system (option).

Can be used for sealed circuit as well


Application example of port tank

Other than circulation to water bath, circulation to device (= sealed circuit circulation) is available by using port tank (option). Circulation to machine with high plumbing load can be easily started by built-in priming pump.

(*1) ±0.03ºC is a value when using enough water and agitation inside water bath is good. Temperature regulation accuracy may vary depend on circulating liquid, setting temperature, environmental temperature, bath volume and circulating flow.
(*2) Allowance of voltage variation is ±0.05% for AC 100V.
Environmental temperature for this product is +5ºC - +30ºC. When using at above +30ºC, cooling capacity may reduce. Lid of water bath may needed depend on bath shape and setting temperature.
Please do not use pure water or distilled water. These may cause breakdown of machine.
Please use heating medium when setting below +7ºC.
External program control is possible for CL-80R/ 150R by using optional program unit (only for below +40ºC) .
