Ovens - Vacuum - Townson & Mercer
 

A highly versatile range of compact vacuum ovens. These vacuum ovens enable heat sensitive materials to be dried at low temperature. You can use our vacuum ovens for any laboratory or industrial application.

Heating Quality:
The chamber is heated by large area heaters strapped to its outer surface. No-wear switching (solid state relay) is used for activating and deactivating the heating elements. As an option, internal heating plates can be installed as well as the external heating elements.

Vacuum Control:
An exhaust solenoid valve is situated for convenience connection to a vacuum pump. The inlet solenoid valve accept air entry or inert gas connection. A vacuum gauge is fitted showing vacuum pulled from 0 to 1000 mBar. The valve is a 3-position manual for the 20 litres model. 

Temperature Control & Safety:
Temperature sensor is a J thermocouple inside the chamber. The temperature is controlled by a precise microprocessor based-controller that provides a high accuracy and prevents the set temperature from being exceeded. The independent over temperature thermostat cut out has an adjustable upper limit, giving a class 3.1 protection. The auto tune PID digital controller digitally displays the set and actual values of temperature, and incorporates a heater indicator lamp. The control panel houses an ON/OFF switch and a fault indicator lamp which lights when the safety thermostat comes into operation.

Equipment:
Multiple position shelving for convenient loading / unloading.
Additional shelves are available.

All C3000 Controller Functions:
The PID digital controller FRANCE-ETUVES C3000 offers the following functions:
• Thermometer probe Pt100 Ω
• Set and actual temperature display
• Delayed start: from 1mn to 99h59 mn
• Heating ramp: from 0,1 a` 20°C/mn

Ovens - Vacuum - Townson & Mercer
 

The EV 018 vacuum oven has the ideal design for gentle drying of heat labile samples and experiments under inert gases and optimizes under inert gases and optimises the control of temperature and pressure is obtained by the sheet heaters surrounding the chamber with the combination of PID microprocessor control system. 

The Stainless steel chamber has high resistance to corrosion, most of the chemical vapours and contamination as well as the silicon gasket which is made in one piece and simply fitted directly on the oven body. The round corners of the chamber and the design of the gasket make the cleaning easier. 

The vacuum level can be followed on the vacuum gauge on the control panel. Two spherical valves are provided as standard: One for vacuum connection and the other for adding dry air or inert gasses. 

The samples can be observed through the heat-treated glass window on the door. The programmable microprocessor control system has two digital displays for temperature and time as well as many functional LED’s. Although the microprocessor control system has many safety features, an independent safety thermostat takes over control in case of any failure.

Ovens - Vacuum - Townson & Mercer
 

Vacuum ovens are used for a wide variety of vacuum drying, curing, and moisture content testing. Common applications include drying heat sensitive samples, moisture determination, and drying samples under a controlled atmosphere. All Townson and Mercer vacuum ovens are specifically designed for unparalleled performance when utilised for these, and other, applications.

Since there is no air in the vacuum chamber, heat is transferred from the heating elements to the interior chamber wall, then to the shelves, and finally to the samples. To minimise conductivity resistance, aluminium shelves are provided with all the vacuum ovens. The oven chambers are wrapped in high temperature insulation which aids overall performance and promotes energy efficiency.

Townson and Mercer offers a range of high performance, microprocessor controlled models. All models include unique design features which enhance the overall performance of the ovens. These features include durable construction with corrosion resistant stainless steel chambers, true vacuum valves, cross-flow ventilation through the oven chamber, and interchangeable door gaskets for application specific use. Independent, resettable circuit breakers prevent any electrical overload.
