Peter Huber Minichiller 300 OLÉ Circulation Cooler

The Peter Huber Minichiller 300 OLÉ (Order No. 3006.0089.98) is the pinnacle of compact cooling technology, holding the title of the world’s smallest Unichiller. This air-cooled model is housed in a robust stainless steel casing and is specifically engineered to provide an economical and environmentally friendly alternative to tap water cooling. With a temperature range of -20°C to +40°C (permitting return temperatures up to 80°C), it is the ideal solution for rotary evaporators, vacuum pumps, and distillation apparatus. The unit is equipped with the modern OLÉ controller, featuring a high-contrast OLED display and "Plug & Play" technology for effortless integration into any laboratory workflow.

Key Features:

• Ultra-Compact Footprint: Requires only 225 x 360 mm of bench space, making it perfect for crowded laboratories and fume hoods.
• Eco-Friendly Refrigeration: Utilizes 43g of natural refrigerant (R290), offering zero ozone depletion potential and an extremely low global warming potential.
• Power Supply: Optimized for international laboratory standards, operating on 220-240V 1~/2~ 50/60Hz.
• OLÉ Controller: Features a bright OLED display with intuitive menu navigation and simultaneous display of setpoint, actual temperature, and safety limits.
• Glassware Protection: The integrated suction and pressure pump provides high flow rates at low pressure, specifically designed to prevent the breakage of delicate glass condensers.
• High Durability: Constructed with a stainless steel housing, evaporator tank, and high-quality industrial plastic pump components for long-term reliability.
• Modern Connectivity: Comes standard with USB (Device) and RS232 digital interfaces for seamless data logging and automation.
• Safety and Compliance: Classified as Safety Class I (NFL) and compliant with UN3358 transport regulations for units containing flammable refrigerants.

The Minichiller 300 OLÉ represents a sustainable investment for any lab. By switching from open-tap cooling to this closed-loop system, users can save up to 48,000 liters of water in a single work week, significantly reducing operating costs while improving the reproducibility of scientific results.

Frequently Asked Questions

1. What is the benefit of using 43g of natural refrigerant?
The use of R290 (Propane) is not only environmentally friendly but also highly efficient. Because it uses less than 150g, it is exempt from many of the stricter leak-testing and placement regulations required for larger systems.

2. Can I use the Minichiller 300 OLÉ for heating?
In its standard configuration, this is a dedicated cooling unit. However, a 1 kW heater can be factory-fitted (Model 300-H OLÉ) to extend the range up to +100°C if heating is required for your process.

3. Is the pump speed adjustable?
No, the pump in the OLÉ model is a fixed-speed suction and pressure pump. It is factory-calibrated to provide the optimal balance of high flow and low pressure to protect fragile laboratory glassware.

4. How does the "Return Temperature 80°C" feature work?
While the unit actively cools the fluid down to -20°C, it is designed to safely receive hot fluid returning from an external process (up to 80°C) without damaging the internal refrigeration or pump components.

5. What does the UN3358 designation mean?
UN3358 is a shipping classification for refrigeration machines containing flammable, non-toxic, liquefied gas. This ensures the unit is handled and transported according to international safety standards for natural refrigerants.
