Präzitherm^® - Precision hotplates

Precise temperatures - easy operation - durable

The table-top devices are manufactured as compact devices, i.e. the control is located directly in the housing under the heating plate. Thus the smallest possible space is taken up. All table-top devices are equipped with an adjustable safety device against overheating (50..300°C or 30..110°C PZ28-1). In the event of a fault, these overheating devices take over a so-called emergency control and thus protect the unit and the material from dangerous temperatures.

Special feature PZ60: This hotplate is equipped with 5 screw-in sockets for support rods, at intervals of 125 mm.

Precise temperatures - easy operation - durable

The Type ET precision hotplate with separate control can be used as table-top or built-in device ( table surface flush). They are controlled either by the 2860SR table-top temperature controller, the 2860EB built-in temperature controller, or the PR5-SR program controller. All devices, except the PZ14ET, have a temperature limiter adjustable from 30 - 110°C or 100 - 350°C.

The connection between the hotplate and the controller is made via two 1.5 m silicone-insulated cables (sensor and regulated power cable). These are led out of the heating plate and plugged into the controller.

Program and temperature controllers

Precise temperatures - easy operation - durable

The PZ44 is a hotplate with automatic control for precise temperatures from 20 to 450°C. The desired temperature is set on the digital controller and is automatically kept constant. The actual temperature is constantly displayed on 10 mm high digits.

The durable electric heater is switchable in three heating levels - 825 - 1650 - 3300 watts. Each heating level set can be further adjusted from 10 to 100% via an electronic power controller to prevent excessive temperature overshoot or to reheat due to excess power. The 825 and 3300-watt heating stages heat the entire surface of the plate. The special 1650 Watt heating level heats only the right half of the plate. Due to creep heat, the temperature then drops by approx. 40% from the right half to the left plate edge (thermal gradient).

Construction: Heating surface made of solid, plane-machined, low-distortion cast iron GG15. Cold housing, also in continuous operation, made of stainless steel. The housing is also painted orange. Four slightly height-adjustable feet for wobble-free set-up. Stable design, load capacity of the hotplate max. 150 kg. Ready for connection with 1.5 m cable.

The PZ44 is also available as a table or built-in unit with a separate control.

For continuous operation at temperatures up to 600°C

High-performance hotplate for temperatures of up to 600°C, short heat-up time (600°C in 20 minutes). Due to the elaborate insulation, the unit can also be placed on heat-sensitive standing surfaces. The insulated hinged lid considerably reduces heat loss. When the lid is closed, a gap of 26 mm (higher lid of request) remains to the heating plate surface, which allows intensive heating of flat parts at exact temperatures.

The temperature control is carried out either with a temperature or program controller. The plate is kept constant at a set temperature throughout the entire control range with the temperature controller.

With the program controller, so-called temperature profiles can be run, i.e., specific heating-up, cooling off and holding phases (max. 5 ramps) can be controlled, each phase lasting up to 9h 59min.
