Peter Huber Minichiller 300w OLÉ Circulation Cooler

The Peter Huber Minichiller 300w OLÉ (Order No. 3006.0090.98) is a premium, water-cooled circulation cooler that offers a high-performance cooling solution within an ultra-compact footprint. Specifically engineered to save laboratory space while delivering superior thermal stability, this "w" (water-cooled) model is ideal for environments where ambient heat discharge must be minimized. With a working temperature range of -20°C to +40°C (permitting return temperatures up to 80°C), it is perfectly suited for cooling rotary evaporators, vacuum pumps, and glass condensers. The Minichiller 300w utilizes natural refrigerants and the intuitive OLÉ controller, combining environmental responsibility with modern, user-friendly operation.

Key Features:

• Water-Cooled Efficiency: The "w" design utilizes a water-cooled refrigeration machine, making it quieter and preventing heat buildup in small laboratories or fume hoods.
• Power Supply: Designed for international versatility, operating on a 220-240V 1~/2~ 50/60Hz power supply to suit standard high-output laboratory outlets.
• Sustainable Cooling: Uses eco-friendly natural refrigerants (R290) as standard, offering zero ozone depletion potential and extremely low global warming potential.
• OLÉ Controller: A bright, high-contrast OLED display with simple menu navigation, providing a simultaneous view of setpoint, actual temperature, and safety limits.
• Superior Glassware Protection: Equipped with a unique suction and pressure pump that ensures high flow rates at a safe, low pressure—perfect for delicate glass condensers.
• Robust Construction: Features a durable stainless steel housing and evaporator tank designed for years of reliable, continuous operation in demanding lab environments.
• Modern Connectivity: Includes standard USB (Device) and RS232 interfaces for digital communication, data logging, and remote monitoring.
• Safety First: Features Safety Class I (NFL) protection with optical and acoustic alarm functions, as well as an autostart function for recovery after power failure.

By replacing expensive and environmentally wasteful fresh water cooling with a closed-loop system, the Minichiller 300w OLÉ can save up to 48,000 liters of water in a single working week, ensuring that the investment pays for itself quickly through reduced utility costs.

Frequently Asked Questions

1. What does the "w" in 300w stand for?
The "w" indicates that this model is water-cooled. Instead of using a fan to blow heat into the room, it uses a secondary cooling water connection (G1/2 male) to carry heat away, keeping your lab quiet and cool.

2. Can I use the Minichiller 300w for applications up to 80°C?
Yes. While the active cooling range is -20°C to +40°C, the unit is designed to handle return temperatures from your process of up to +80°C without damage.

3. Does this unit require a specific electrical phase?
No. It operates on a standard 220-240V 1~/2~ 50/60Hz supply, making it compatible with most laboratory electrical infrastructures without needing 3-phase power.

4. How much cooling water does the unit itself require?
At a cooling water inlet of 15°C and 3 bar differential pressure, the unit consumes approximately 15 liters per hour. This is significantly less than the thousands of liters a typical open-tap cooling setup would use.

5. Can I connect an external temperature sensor?
Yes, a Pt100 sensor connection (#10519) can be factory-fitted to the OLÉ controller. This allows you to display—though not control—the temperature of your external process directly on the OLED screen.
