Gas Bottle Flexible Heating Jackets

Gas Bottle Flexible Heating Jackets

Many laboratory and industrial processes require a constant flow of gas to be delivered, and this is normally supplied from pressurised cylinders containing gas in liquid phase. If the level of liquid reduces fast, frosting can occur on the surface of the cylinder and flow rates can be adversely affected. Our gentle and insulated heating solutions can prevent this phenomenon and restore stability to the flow rate. This is particularly important when using calibration gases where repeatability is vital. Note that separate over-pressure safety systems should always be in place to meet health and safety requirements.

We can design jackets for most cylinder sizes, with our standard “HHG” being a popular size normally available for immediate delivery.

Product Specification: “K” size gas cylinder (others available to order)

Adjustable length: 680-830mm, Overall Height: 1050mm
Power supply: 110vac or 240vac
Power rating: Standard HHG with 0-90°C (or -5 to 40°C) adjustable thermostat: 450 watts

THERMOSAFE® Type A Induction Heater

THERMOSAFE® Type A Induction Heater

The THERMOSAFE® is a single induction coil, wholly encapsulated in a cylinder made from a glass reinforced resin specifically developed for chemical plants. The cylinder is simply placed over the drum. Contact is not required.

The coil is connected to a single phase AC mains supply and generates heat direct and uniformly in the drum wall. Energy transfer is by alternating magnetic field and thus there is no heat transfer by the conventional and inefficient means of radiation or convection. As there are no hot elements, the heater remains substantially cooler than the drum being heated.
THERMOSAFE® Type B Induction Heater

THERMOSAFE® Type B Induction Heater

Uses the same technology as the proven THERMOSAFE® Type A Induction Heater
Lighter and easier to handle, ideal where height is restricted
Two heaters can be stacked to heat full height of drum
110/120v operation

To complement the longstanding and successful 240v THERMOSAFE® Type A, our 110/120v Type B model is available, ideal where height is restricted, or for heating smaller containers. Two Type B heaters can also be stacked and operated at 110v or 240v.

A single Type B heater can heat the lower section of a 205L steel drum to around 110°C. Two heaters can be stacked to enable the full height of the drum to reach approximately these temperatures.

Just like the THERMOSAFE® Type A, the Type B is suitable for use in hazardous areas, certified to ATEX, IECEx, UL and CSA standards (zones 1, 2, 21 & 22).
FARATHERM Induction Base Heater
