Cold Circulating Constant Temperature Bath: RCC-45
The RCC-45 is a compact, space-saving low-temperature circulation thermostatic chamber designed to occupy a minimal footprint on the laboratory bench.

Manufacturer: Rigo — Japan
Overview
The RCC-45 is a compact, space-saving low-temperature circulation thermostatic chamber designed to occupy a minimal footprint on the laboratory bench. It provides ample cooling capacity down to -40°C, delivering 220 W of cooling power at -20°C, and is intended primarily as an auxiliary cooling unit for RIGO's low-temperature property testers. An external circulation pump, which doubles as the bath's stirrer, lets coolant be circulated to external equipment with ease. Because it is purpose-built to support RIGO's low-temperature testers, it integrates readily into an existing test setup without requiring additional refrigeration infrastructure.
Cooling Performance
The RCC-45 maintains reliable cooling down to -40°C and still delivers 220 W of cooling capacity at a bath temperature of -20°C, giving it enough reserve capacity for demanding low-temperature test cycles. This performance makes it well suited to feeding coolant to auxiliary low-temperature testers running continuously over long test sequences.
External Circulation
A built-in circulation pump serves double duty as the bath's stirrer and as the means of pumping coolant out to connected equipment, so no separate external pump is required. This simplifies plumbing and reduces the number of components a laboratory needs to maintain.
Compact Footprint
The unit is engineered to minimize its occupied space, making it practical to install alongside other bench-top petroleum testing instruments in laboratories where space is limited.
