DRUM HEATING CABINETS

Thanks to over decades of experience in the continuous study of product and process, from large chemical plant to small workshops, by means of a standard solution or a completely customised solution, AMARC Drum Heating Cabinets are chosen for heating raw materials contained in drums or tanks. By pursuing the best thermal efficiency possibile and the highest level of functional safety.

APPLICATION AND REFERENCE SECTORS

The heating cabinets are necessary in production chains in which products, mixtures, raw matertials contained in 200 L drums (or other capacity) or 1000 L containers (or other capacity) are to be subjected to heating treatment to change the phase or viscosity or subjected to a melting process in order to be transferred for the next step of the process.

For over 30 years, AMARC heating cabinets have been installed and used in the chemicals, cosmetic, pharmaceutical, food and beverage, petrolchemical, blending, oil&gas sectors.

ATEX heating cabinet for 32 drums for the chemicals sector

ATEX horizontal heating cabinet for 8 drums for the petrochemicals sector

Vertical heating cabinet for 8 drums made of AISI304 stainless steel for the pharmaceutics sector

CONSTRUCTION

The heating cabinets consist of a welded steel frame to which the load-bearing walls are coupled, made of suitably assembled metal sheets and panels made of insulating and “absestos free” mineral wool.

The constructional policy achieves a double goal:

Structural sturdiness. The cabinet is designed to resist stresses and undesirable impact for long periods during the loading and unloading operations.
For this purpose protective structures are provided on the internal walls on all the units to prevent impact caused by pallets.
The load-bearing structures, with shelves for housing the drums, are subjected to structural calculation.
Thermal Insulation. The structure is designed without thermal bridges and suitably insulated, thereby ensuring minimum dispersal, efficient heat exchange and resulting energy saving.

OPERATION

The heat transfer process mainly takes place by air convection.
A ventilation unit installed In the upper part of the cabinet sucks in air, directing it on the heating element or a heat exchanger supplied with fluid (hot water, saturated steam, diathermic oil) and is conveyed to a delivery duct which directs the heated air uniformly on the drums or containers, creating the turbulence necessary for optimum heat exchange.
The process is “controlled” by a digital temperature regulator installed inside the control panel and paired with a probe installed in a suitable position.

STANDARD DRUM HEATING CABINETS

The definition of standard models proposed by AMARC is the final result of over 30 years of design, production and more than 1000 installations throughout the world.
The know how built up has made it possible to fully understand the needs of our customers and of the market in general.
An extensive range has been studied which allows a high degree of versatility of choice within a standardised offer!

The standard heating cabinets can be configured according to:

Operating temperature

a. Up to +100℃
b. Up to +150°C

Technical Notes

a. Up to +100℃
b. Up to +150°C

The operating temperatures indicated above are ensured for the heating cabinets with electric heating.
For the cabinets heated with steam, hot water, hot oil, the operating temperatures indicated above depend on the capacity of the customer’s plant.
The cabinets heated with hot water which are normally supplied at a max. of +90°c can reach an operating temperature ≤ +60°C (∆T ≈ 30°C).
AMARC Engineering Department Can Check The Performance.

Capacity

2 – 4 – 8 – 12 – 16 – 24 – 32 – 40 – 48 drums
See Capacity table

Technical Notes

a. 2 drums
b. 4 drums
c. 8 drums
d. 12 drums
e. 16 drums
f. 24 drums
g. 32 drums
h. 40 drums
i. 48 drums

With the exception of the “2 drums” heating cabinet, all the models are modulated to house 4 200 L drums on 1200×1200 mm chemical pallet.
This housing is also suitable for loading 1000 L IBC.
For customers who handle drums on 800×1200 mm euro-pallet, special models are available on request.

Heating

a. Electric
b. Steam
c. Hot Water
d. Diathermic Oil

Technical Notes

a. Electric
b. Steam
c. Hot Water
d. Diathermic Oil

For cabinets operating with steam, hot water, diathermic oil, since the capacity of the customer’s plant upline of the heating cabinet limits the performance of the heating cabinet, the customers must inform the AMARC engineering department concerning the temperature (in °c) and pressure (in barg) data with which the heating cabinet is supplied.
It is possible, on request, to provide for a special heating cabinet with double heating: electric + steam, electric+hot water, electric + diathermic oil.
It is possible, on request, to provide a special heating cabinet supplied with gas (natural or lpg)

Steam Heating

Hot Water Heating

Diathermic Oil Heating

Installation site

a. Indoor
b. Outdoor

Technical Notes

a. Indoor
b. Outdoor

The cabinets for outdoor installation are provided with

sealing treatment of the metal plates (to prevent undesirable seepage)
protective roof
control panel with IP65 protection (for versions with “watertight” enclosure) or IP66 (for versions with explosion-proof enclosure for ATEX external zone)

Explosion-proof protection (Atex) for gas

a. Internal and external cabinet not ATEX classified
b. Internal zone 1-gas or zone 2-gas, external zone not ATEX classified
c. ATEX classified internal and external cabinet (zone 1-gas)

Technical Notes

a. Internal and external cabinet not ATEX classified
b. Internal zone 1-gas or zone 2-gas, external zone not ATEX classified
c. ATEX classified internal and external cabinet (zone 1-gas)

For type b.(internal zone Atex classified), during the request phase, the customer must submit the safety data sheets of the products that may give rise to gases, vapours, fogs so that these can be subjected to analysis by the AMARC engineering department for a correct classification of the area and the consequent sizing of the relevant safety devices
For Type c. (external zone ATEX classified) it is the customer’s responsibility to classify the heating cabinet installation area
AMARC heating cabinets are not suitable for installations with risk of explosion of powders (zone 21 and 22)
AMARC heating cabinets are not suitable for installations in zone 0
