Grant R52 — high‑stability refrigerated circulating bath

The Grant R52 refrigerated circulating bath is a high-precision temperature control system designed for applications demanding broad-range, stable, and programmable thermal regulation. Offering an operational temperature range of −52 °C to +100 °C, the R52 is an extremely versatile solution suitable for both scientific and industrial settings. Its advanced circulation system and precision PID controller ensure outstanding stability of ±0.1 °C, critical for repeatable experimental conditions.

The 12-liter stainless steel bath is built for durability and long-term use under demanding laboratory conditions. A front-facing, no-spill drain valve allows for quick and safe emptying of the tank, minimizing mess and risk. With a cooling capacity of up to 1100 W at +20 °C ambient temperature, the R52 can quickly reach setpoints and maintain them even when thermal loads are introduced via external circuits.

The unit features an intuitive digital interface with full programmability, enabling time-based thermal profiles, error notifications, and remote control compatibility. It supports both internal and external circulation loops, making it suitable for reactor jacket heating/cooling, sample pre-conditioning, photometric stability tests, bioreactor integration, and more.

Integrated safety features include over-temperature protection, compressor idle shutoff, dry-run heating prevention, and self-diagnostics. The unit operates on standard 230 V / 50 Hz electrical supply and complies with international safety standards (IEC/EN).

The Grant R52 is ideal for laboratories requiring accurate temperature calibration of sensors, thermal stability for chemical analysis, or highly stable heat exchange during sensitive experiments and equipment testing.
