Type 9VJAF: Flexible jacket heaters with digital display electronic controller, adjustable up to 120°C, remote wall mounting, for metal containers

Main Features

Thanks to its electronic digital temperature controller, adjustable up to 120°C, these flexible jacket heaters are used for antifreeze protection, reheating, temperature stabilization, to reduce viscosity or to melt soaps, animal or vegetable fats, varnishes, oils, food or chemical products.

This series of jacket heaters is the most universal solution, with digital electronic temperature controller for heating at a set temperature glass or plastic containers. They are available for containers of 110L (30 US gallons) and 210L (55US gallons).  The wall mounting of the control box, as well as the quick connector ensuring the connection of this box on the jacket heater facilitate industrial use in a fixed working place in a production line. The jacket heater covers the entire surface and is surmounted by a soft collar “a scarf” preventing it from sliding down. They are made with three power levels: (0.05W/cm² for temperature up to 50°C, 0.1W/cm² for temperature up to 80°C, and 0.135W/cm² for temperature up to 110°C. Their thickness of insulation is 20mm. In these models the surface temperature is limited to 135°C.When they are used with an insulated lid and an insulated pedestal, their energetic efficiency can rise 90%

Technical characteristics

The heating element of the flexible jacket heater consists of a network of silicone insulated heating wires shielded by a metal braid, taken under a cover sewn in PU and Teflon coated polyester fabric. A 20 mm thick, temperature-

resistant NBR-PVC foam insulation is inserted between the heating network and the outer wall. This insulating foam has an insulation coefficient (Lambda λ) of 0.039W/m.K, and this makes it possible to divide the energy losses by 3 compared to jacket heaters insulated with mineral wool or carbon fiber felt of the same thickness. Adjustable metal buckles allow quick assembly and disassembly and efficient clamping on the container. Their mechanical strength is exceptional.

Fabric covering:

– Internal heating face: Teflon coated polyester fabric,

– External side: waterproof PU coated polyester fabric.

Thermal insulation:

NBR-PVC foam, with closed cells and high temperature resistance, thickness 20mm.

Heating element:

Silicon insulated heating wire with metal braid providing mechanical protection against puncturing and good grounding.

Temperature control:

By electronic controller with digital display, On-Off action, relay output, located in an independent waterproof housing, designed for wall mounting. It is connected to the heating blanket by a cable equipped with a 5-pin waterproof quick connector, facilitating the connection and disconnection with the jacket heater. It controls the temperature by means of a thermistor probe placed on the inner surface of the fabric in contact with the container. This probe has an anticipation loop avoiding overheating. A temperature limiter is incorporated in the heating net to limit the surface temperature to 135°C.

Connection cable:

Insulated rubber power supply cable, for industrial environments, 3 x 1mm² or 3×1.5mm² (depending of power) length 3m, Euro plug. UL plug on request.

Mounting on containers:

These jacket heaters feature nylon straps with quick-release adjustable buckles for adjustment to the diameter of the container, and a soft fabric collar without thermal insulation named scarf. This flexible scarf can be used to hold in place an insulating lid in the case of cylindrical containers.
