Proline Kryomate Thermostats
High-Performance Low-Temperature Thermostats
Professional Cooling Thermostats | −90 °C to 200 °C
The LAUDA Proline Kryomate are high-performance cooling thermostats designed for demanding laboratory and process applications requiring reliable operation at very low temperatures. Engineered for material testing, quality control, and process engineering, the series combines powerful cooling output, precise temperature control, and robust construction.
Working Temperature Range
• Minimum temperature: down to −90 °C (model dependent)
• Maximum temperature: up to 200 °C
• Temperature stability: approx. ±0.05 K
This wide temperature range makes the Kryomate series suitable for both deep-cooling applications and controlled heating processes.
Cooling & Heating Performance
(Performance values depend on the exact RP model and whether the unit is air-cooled “C” or water-cooled “CW”)
• Cooling output (at 20 °C): approx. 3 kW up to 6 kW
• Maximum heater power: up to 3 kW
• Refrigeration system: High-performance multi-stage refrigeration for ultra-low temperatures
• Maximum pump discharge pressure: approx. 0.5 bar
• 4-stage pressure pump optimized for strong internal circulation
The powerful refrigeration system ensures rapid cooldown times and stable performance even at extreme temperatures.
