GRANT High-Temperature Oil Bath HED Series
The GRANT High-Temperature Oil Bath HED Series is specially designed for precise temperature control tasks in chemical, pharmaceutical and biotechnological research laboratories. Using state-of-the-art technology, the series enables exact control in the temperature range up to 26 °C. The combination of advanced safety technology, ease of use and outstanding temperature stability makes this high-temperature oil bath the preferred solution for professional users. Compared to similar laboratory heating baths, this series offers particular advantages in terms of safe operation, precise adherence to setpoints and great flexibility in demanding temperature regimes.
Precision and safety at the highest level
The HED series from GRANT sets standards for high-temperature baths in scientific and industrial laboratories. Two model variants - HE10D and HE30D - cover different bath sizes and performance requirements. Both models feature a precise temperature control range from 50 to 260 °C and enable extremely stable conditions, which are essential for reproducible experiments and quality tests.
Technical highlights at a glance
- Temperature range: 50 to 260 °C
- Temperature stability: ±0.25 °C at 150 °C according to DIN 58966
- Uniformity: ±0.2 °C at 150 °C
- Heating capacity: 1.1 kW (HE10D), 2.2 kW (HE30D)
- Liquid flow rate: up to 6 l/min (with additional external pump)
- Pump pressure: 1.6 m at 0 l/min (with external pump)
- Safety features: Adjustable over-temperature shut-off & float switch for liquid level
Both models are equipped with an LED display (resolution 1 °C) and a timer function (1 to 9999 minutes). Alarms for exceeding and falling below set limits, adjustable over-temperature protection and continuous monitoring of the liquid level guarantee safe operation even during long-term experiments. The design of the baths ensures excellent temperature distribution and minimal gradients in the liquid. Further technical details of the series: The dimensions of the HE10D are 305 × 210 × 185 mm (bath depth min/max: 100/140 mm) and 455 × 305 × 240 mm (min/max: 145/190 mm) for the HE30D. The models weigh 19 kg (HE10D) and 30 kg (HE30D) respectively and meet EMC requirements Class A. Certifications and standards compliance
The temperature stability and uniformity comply with DIN 58966, which is particularly essential for applications in materials testing and accredited testing environments. These features are complemented by electromagnetic compatibility testing in accordance with EMC Class A. This makes the series suitable for laboratories with increased requirements for interference-free operation and compliance.
Possible applications in research and industry
The HED series is ideal for all high-temperature applications in the laboratory. Thanks to advanced control electronics and powerful pump technology, a wide variety of temperature control tasks can be reliably implemented, even with external circulation:
-
Chemical synthesis: Ensures stable reaction conditions for exothermic and endothermic processes, e.g. for catalyst or polymerisation reactions (common substances: silicone oil, polyethylene glycol).
-
Materials testing: Test setups for thermal stress and stability testing (e.g. metals, plastics) under defined temperature profiles.
-
Biotechnology & life sciences: Incubation and heating of samples for enzyme activity or protein extraction at high temperatures.
-
Pharmaceutical development: Conducting controlled stability studies, temperature control of samples during drug release.
Typical fluids used are silicone oils and other temperature-stable fluid media.
FAQs about the GRANT HED series high-temperature oil baths
How accurate is the temperature control?
The temperature control achieves a stability of ±0.25 °C (DIN 58966, measured at 150 °C). A major advantage is the uniformity of ±0.2 °C, ideal for all applications where even slight temperature fluctuations are critical.
What safety features protect my samples and the device?
The bath is equipped with an adjustable electronic overtemperature shut-off, a liquid level float switch and an acoustic and visual alarm in case of limit violations. This prevents both drying out and overheating.
Can external equipment also be temperature-controlled?
Yes, thanks to a powerful internal (and optional external) pump, connection to external reactor circuits or heat exchangers is possible without any problems. Depending on the pump configuration, the maximum flow rate is 6 l/min.
Which media are compatible?
Silicone oil is primarily used, as it is characterised by high temperature stability and low evaporation. Depending on the application, other heat-resistant oils can also be used - in principle, the chemical compatibility with the bath material used must be checked.
Summary
The GRANT HED series of high-temperature oil baths combines precise temperature control, comprehensive safety features and robust construction in a device that meets the highest demands in laboratories and quality control. The HE10D and HE30D models offer sophisticated, user-friendly features and are ideal for a wide range of temperature control tasks. This series is an excellent choice for those who value standard-compliant, reproducible results and safe operation.
