New Patented High Current Hazardous Area Controller

This ATEX and IECEx certified controller is ideal for use with our Thermosafe, Faratherm or InteliHeat FlexiPlus products and other heating equipment installed in potentially explosive atmospheres. The device features Near Field Communication (NFC) which allows operators and site managers to set the key parameters of the device quickly and easily using pre-programmed cards. Simply hold the credit card sized NFC cards close to the front of the controller and the settings are instantly updated. This also makes the controller “Covid-secure”!

Two NFC cards will be provided pre-programmed to the users settings. Additional cards can be supplied with alternative settings, and optionally, a dedicated smart phone or tablet with our embedded interface can be purchased to permit customer programming on site. The simple 3 – button interface on the front of the device can be used to adjust set point and other parameters whilst the device is operational WITHIN THE HAZARDOUS AREA, plus for additional security these push buttons can be disabled or limited. Dependent on the heater size and configuration, the ProxATEX can be preinstalled directly onto the heater, mounted onto a wall, or alternatively a pre-wired single pillar roaming controller stand can be supplied for multi-location applications.

Features include:

-Digital display to show measured values and other parameters

-Lock function with password to ensure settings remain unchanged

-Adjustable timers for delayed start, and soak period

-Maximum power output adjustable 0 – 100%

-1 or 2 thermocouple input options

-Setpoint offset & Hysteresis adjustment for custom control environments

The speed and flexibility of the Thermosafe Induction Heater means that in busy production environments frequent drum changes are often required.

The Thermosafe may be moved and lifted manually under appropriate supervision. With a weight of 48kg it can be lifted over a drum by two persons. Alternatively a number of handling options are available to reduce worker fatigue and comply with any site specific workplace practices.

Thermosafe Lifting Frame

Designed only for use with a Thermosafe Induction Heater, the Lifting Frame offers a simple solution to maneuvering and lifting a Thermosafe.  Each heater can then be positioned quickly and easily by just one operator.

The sturdy steel frame is fitted with a braked winch easily capable of lifting either one Thermosafe Type A or up to two Type B heaters. Robust and lockable casters are fitted to the frame, and simple retaining bars and clips are used to secure and quickly release the Thermosafe.

The Lifting Frame is suitable for use in hazardous areas, certified to the requirements of the ATEX Directive 94/9/EC for non-electrical equipment and Machinery directive 98/37/EC. The Lifting Frame can be supplied in two base widths; a wider width to incorporate drums on pallets, or a standard unit for applications where this is not necessary.

SIMPLE PRINCIPLE

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.

SAFETY

The complete absence of hot elements and the encapsulation of all electrical components enables unattended use, overnight if required. THERMOSAFE® can even be used in hazardous areas. Uniform heating without hot spots reduces the risk of product degradation. Accidental spillage does not present a fire hazard and personnel can work comfortably in close proximity. Together, these features allow material to be heated at point-of-use, thus eliminating the transport of hot drums.

EFFICIENCY

The low system temperature and lack of heat transfer contribute to high efficiency of the induction heater. Power usage is extremely low at only 2.25kW. Although originally designed with safety in mind, the heaters have won several awards for efficiency and productivity. Independent figures indicate energy savings of over 50% when compared with conventional radiant drum heaters, and more than 90% in comparison with drum ovens.

SPEED

By using the entire drum wall to input energy, the fastest practical heating rate can be achieved without product degradation. Heating times will depend on the contents of the drum but, to give a rough idea, the rate to temperature rise of a typical viscous organic liquid will be about 15°C per hour. The speed is further improved by the initial response of induction heating. Typically the THERMOSAFE® has proved to be 2-4 times faster than ovens.

CLEANLINESS

With ingress protection to IP66, simple smooth surfaces and no moving parts, the induction heaters are ideal for use in clean environments. They can even be hosed down during use.

FLEXIBILITY

In addition to being operated a point-of-use and integrated into the process, the heaters are used extensively as replacements for, and alternatives to, drum ovens. A key point to note is that far fewer individual heaters are required than the drum capacity of an oven. For example, one particular award winning installation of three THERMOSAFE® units heats 20 drums per day. The ease at which capacity can be adjusted to meet varying throughput demands and the varying heating requirements of different materials is in stark contrast to the fixed facility of an oven.

MULTI-PURPOSE

The induction heater’s unique features enable the same piece of equipment to be used in a wide range of applications to heat drums and a variety of other metal items, including gas bottles, small-scale reactors and process vessels. Complete access to the drum while heating enables pumps and stirrers to be employed. The drum and heater can be integrated into the system, often eliminating the first process vessel, and continuous feeding of material, at regulated temperature and flow rate, can easily be achieved.

Uniform heating and instant response makes the heater ideal for removing residues from drums, significantly reducing wastage. With full drums, these same features enable very rapid removal of solid drum contents by melting the outer layer of the material for rim liquefying.

MAINTENANCE

Since 1985, THERMOSAFE® heaters have been supplied to more than 60 countries. With no heating elements and no moving parts, experience has shown a seemingly unlimited life, with literally no maintenance, even in harsh environments.

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℃.  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).
