Safety Introductions
Please read these operating instructions before commissioning the device! Failure to observe these safety
instructions may result in damage to property and personal injury due to fire or electric shock!
Container heaters are only to be used in the upright position with the bottom of the container towards
the ground.
Container heaters are electrical equipment which may only be installed, connected and commissioned by trained per-
sonnel. Suitable electrical disconnecting and protective devices must be provided by the operator in accordance with
the relevant legislative regulations. We recommend the use of a residual current circuit breaker (RCD) with 30 mA.
All container heaters are suitable for operation in closed rooms and covered outdoor areas (degree of
protection IP 54). They must not be directly exposed to the weather.
Before commissioning
Remove the heating mantle from the packaging and make sure that it is not damaged. Never lift the heater by the
connection cable. Check that the mains voltage corresponds to the product label.
Always use the heater only for the intended container of the corresponding design and size. This applies in particular to
cambered plastic drums. Never use the heater without the suitable corresponding container!
When using on plastic containers, make sure of the maximum temperature (usually around +70 °C) and heating time
specified by the manufacturer are followed.
Keep informed (e.g. Safety Data Sheet) about which max. permissible temperature of the ingredient must
not be exceeded and whether flammable gases or vapors can escape (risk of fire and explosion!).
Make sure that the outside of the container to be heated is clean and dry.
Do not use additional heating or heat sources and never expose the container heater to temperatures above the nom-
inal temperature.
Assembly
Mount the heater in such a way that it lies smoothly and without folds on the container and that the heated areas
(recognizable by the inner pockets) do NOT overlap. Use the existing fasteners to secure the tank heater against slipping.
Do not use any fasteners other than those supplied and do not use any tools for assembly that could overstress the
material.
Always maintain a safety distance of at least 50 cm between two heated containers. The same applies to the distance
to radiators, warm surfaces, etc.
Commissioning
Do not connect the temperature controller to the power supply until after installation. To do this, remove the temper-
ature controller from its packaging and attach it to the fleece hook and loop pad provided on the heating mantle. Con-
nect the heating mantle (6+PE male) to the controller (6+PE female) using the round plug connection. Use the controller
to set the desired temperature set point. The temperature of the ingredient must be determined by separate fluid
sensor, if necessary.
Monitor the heating phase and the operation of the tank heater to observe any overheating or irregulari-
ties and initiate appropriate measures.
Open the lid or bungholes of the container so that it does not expand inadmissibly due to a pressure build-up during
heating. Monitor the fill level of the container while removing the contents. In the event of any leakage, take the con-
tainer heater out of operation immediately.
Caution: At temperatures above 60°C, there is a risk of burns on the surfaces of the containers. Protect
yourself against this.
Please ensure good ventilation. A heating mantle that is not in operation must be disconnected from the power supply.

Disassembly and storage
Switch off the heater and allow it to cool down completely. Disconnect it from the power supply before disassembly.
Then check it for damage and contamination and the connection cable for defects.
Do not use solvents or abrasive cleaners to clean the heater and never immerse it in liquids. To clean, gently wipe the
surfaces and controls with a damp cloth. Keep the heater away from sharp edges and pointed objects.
If you find defects or damage of any kind, do not put the heater into operation again. Do not attempt to
repair a damaged one yourself.
When the heater is not in use, it should be stored in a dry and clean environment in its original packaging. To do this,
gently roll it loosely along the pockets without squeezing or bending it.

1Introduction
Container heaters are used to heat drums and IBC containers made of plastic or metal in order to protect the contents
filled in them from frost, to heat them to a certain processing temperature or to facilitate their removal and dispensing
by reducing their viscosity.
The heating element is installed within inside pockets, which ensures even heat distribution and gives the heater a
structure that allows them to optimally fit the surfaces of the objects to be heated. They are equipped with a hook and
loop fleece to attach the digital temperature controller, which can be manually set to the desired temperature of up to
90 °C.
The light weight heater has integrated insulation to minimize unwanted heat loss. Equipped with robust pull straps and
snap closures, they can be quickly and easily be attached to and removed from standard containers and drums. Addi-
tional fastening straps or hooks that prevent them from slipping off the container are provided with the heater.
With their relatively low specific surface power, they are only suitable to a limited extent for rapid heating of liquids or
melting of solid ingredients. Much more, they are ideally suited for frost protection as well as slow heating and main-
taining the temperature directly at the tapping point of already heated containers. Insulation lids are available as acces-
sories to improve the efficiency and protect personal against burns on the hot surfaces of the containers.
With their high-quality materials and workmanship, the heaters provide a safe, efficient and durable solution for heating
of drums and containers in industrial applications when operated as intended.

5.4 Assemblage
Place the drum heater around the drum. The pre-installed (or enclosed) retaining straps help with mounting and at the
same time prevent sagging during operation (Figure 5.4.1). Align the two fastening straps according to a good fit on your
container. To protect against moisture and mechanical impact, the drum heater should not be placed directly on the
floor during this process. Close the buckles and tighten the tie straps evenly (Figure 5.4.2). The drum heater must fit
smoothly against the container without wrinkles and the heated areas (indicated by the inner pockets) must NOT over-
lap. The tightest possible fit will ensure efficient operation and uniform heating.

6.3 Structure
IBC heaters consist of an outer mantle (1) made of water-repellent polyester fabric. Pockets are sewn into the heating
mantel, into which the fluoropolymer-insulated heating element is inserted. Double thermal insulation made of polyes-
ter fleece is sewn on the inside of the outer mantel. Robust adjustable tension straps (2) and snap closures made of
polyamide are used for fastening. Eight additional fastening hooks (3) at the top prevent slipping. A drain spout cover
to the front end allows the contents to be removed via the drainage valve.
Next to the cable exit (4), the IBC heaters have one to two fleece pads (depending on the version with one or two heating
zones) to which the temperature controllers (separately purchased) are attached. For each heating zone 2 ea. Pt100
sensors are used for temperature control and thermal protection, and one additional bimetal thermal cut-out device,
which prevents uncontrolled heating in the event of a failure of the Pt100 sensors. Depending on the version, the IBC
heaters are designed in protection class II (standard) or protection class I (option). The IBC heater controllers are con-
nected to the power supply via a 5.0 m connection cable (5).

6.4 Assemblage
Place the IBC heater around the container and secure it with the hooks to prevent it from slipping off (Figure 6.4.1).
Make sure that the flap is placed in front of the discharge spout. Close the buckles and tighten the tie straps evenly
(Figure 6.4.2). The IBC heater must be smooth and wrinkle-free against the IBC. The heated areas (recognizable by the
inner pockets) must NOT overlap.
