Peter Huber Variostat Refrigerated Heating Circulator

The Peter Huber Variostat (Order No. 2013.0003.01) is a unique, high-performance immersion circulator designed for the precise thermoregulation of variable bath sizes. Unlike standard fixed-bath systems, the Variostat offers ultimate flexibility by allowing users to transform almost any vessel into a high-precision temperature control system. With a versatile temperature range of -30°C to +150°C and a powerful 1.0 kW heating capacity, it is ideal for diverse laboratory and industrial applications. The unit is equipped with the sophisticated Pilot ONE controller, featuring a 5.7" multi-touch screen and a professional-grade functional suite for demanding thermal processes.

Key Features:

• Universal Compatibility: Designed to thermoregulate a wide variety of baths, ranging from small vessels to large containers (up to 250 liters with appropriate insulation).
• Pilot ONE Controller: Includes a high-resolution 5.7" touchscreen, intuitive icon-driven navigation, and integrated technical glossary.
• Power Supply: Optimized for global laboratory standards with a 220-240V 1~/2~ 50/60Hz power requirement.
• Advanced Pump Technology: Features a stepless, variable-speed pressure and suction pump (VPC) for optimal circulation in any bath size.
• High Stability: Maintains exceptional temperature stability of ±0.02 K (according to DIN 12876), ensuring reproducible results.
• Eco-Friendly Refrigeration: Utilizes R290, a natural refrigerant with a GWP of only 3, making it an environmentally sustainable choice.
• External Control: Equipped with a Pt100 sensor connection for monitoring or regulating external processes, plus RS232, USB, and Ethernet interfaces.
• Safety First: Classified as Safety Class III/FL, featuring adjustable overtemperature protection and low-level safety sensors.
• Scalable Performance: Compatible with E-grade functionality upgrades to expand programming and data logging capabilities as process requirements grow.

The Variostat stands out for its "Plug & Play" modularity and robust stainless steel construction. Whether you are performing material testing, chemical synthesis, or standard quality control, this circulator adapts to your existing infrastructure. Its compact footprint and powerful air-cooled refrigeration unit ensure consistent performance without occupying excessive laboratory bench space.

Frequently Asked Questions

1. What is the maximum bath volume the Variostat can handle?
The Variostat is highly versatile; while often used with 5L to 20L baths, its powerful pump and 1kW heating capacity allow it to regulate larger insulated vessels up to 100+ liters depending on the required temperature range and insulation quality.

2. Can I use the Variostat to control an external closed system?
Yes. By using the M16x1 pump connections and the variable-speed pump, you can thermoregulate external closed applications. An optional pressure sensor can also be integrated for precise VPC pressure control.

3. Is the Variostat compatible with all thermal fluids?
It is designed for use with non-flammable and flammable liquids (Safety Class III/FL). However, ensure the fluid's viscosity does not exceed 50 mm²/s at the lowest operating temperature.

4. How do I record my temperature data?
The Pilot ONE controller allows for direct data logging to a USB flash drive. For more advanced recording and remote control, you can connect the unit to a PC via USB, RS232, or Ethernet using Huber Spy software.

5. Does this unit require a 3-phase power connection?
No. This Variostat model operates on a single/two-phase 220-240V 1~/2~ supply at both 50Hz and 60Hz, making it easy to install in most standard laboratory environments.
