2.0 Detailed description
2.1 Technical description Self Serve
Panels are made of galvanized steel plating, stainless steel and/or aluminum.
Some of the visible internal and external parts have been provided with a powder coating.
Glass used is tempered.
Unit can be moved by means of a pallet truck.
Product contact parts are made of stainless steel AISI 304 or AISI 430 and tempered glass.
2.2 Cold units Self Serve: (OmiCold Air ow technology)
Cooling is achieved by means of a thermostatic temperature-controlled cold airow.
Cold air is passed via the back and shelves over the products.
Between price rail and child glass an opening exists which is vital for the airow
inside the unit.
Price rail must always be kept in place .
For MCC Cold SS:
Price rail is integrated part of air guidance inside the unit.
Removing the price rail will result in a bad functioning MCC
Self-serve models have an additional set of fans mounted in the top to create a stable air curtain on
the open side of the cabinet to minimize the inltration of warm ambient air. The air on the front side
passes through the suction grid in the bottom of the unit.
Temperature of the airow is controlled electronically.
The electronically controlled thermostat is factory pre-programmed.
Set temperature can be changed from -6 ºC to +0 ºC (21.2 ºF to 32 ºF).
The units can be connected to a xed drainage system or an optional evaporation tray to evacuate
Condensation water.
One LED-module per level provides lighting of the products.
Lighting and cooling are switched on simultaneously
Self-serve models can be tted with an optional night curtain.

2.3 Hot units Self Serve: (Patented Hot Blanket Holding technology)
Heating in hot self-serve units is achieved by means of heated shelves in combination with an
hot-air curtain per shelf. This air curtain isolates the hot air inside the unit from the ambient air.
Hot serve over units have a single heat source in the base of each shelf and use fans to distribute
the heat throughout the cabinet.
An electronic thermostat controls the temperature.
The electronic thermostat has been pre-set at the factory.
This value can be changed for self-serve models between 40 ºC and 70 ºC (104 ºF and 158 ºF) and
for serve over models between 40 ºC and 85 ºC (104 ºF and 185 ºF).
One LED-module per level provides lighting of the products.
The LED-lighting and the heating are switched on and o󰀨 separately, In the future Lightning and
heating are switched on simultaneously.

2.6 TechnicaldescriptionFullServeHotHumidied
The MCC Hot FS is a multilevel serve over heated display cabinet intended for hot presentation
of food products.
A heating element and an array of fans are located in the base of the unit and circulate hot air
throughout the cabinet, creating uniform holding conditions.
Any air in- and outlet openings should be kept clear. A digital controller is installed to regulate the
temperature inside the cabinet.
A water tray is present underneath the base deck which can be used to increase the humidity
levels inside the cabinet, hereby increasing the shelf life of delicate products.
To make sure the cabinet is installed, operated and serviced in a safe manner, the instructions
provided by the manufacturer should be adhered to at all times.
The cabinets can also be supplied with or without under frame to be installed into an
existing counter top.
Heating in hot full-serve units is achieved by means of a nned heating element in combination
with hot-air blowers. The blower fans suck air on the intake side, blowing this air along the heating
element causes the air to heat up.
To prevent products from drying, humidication is applied by means of a water tray underneath the
hot air ow. Hot air holds more moisture. The moist hot air is blown into the unit, creating a higher
humidity inside the “closed” unit.
Serve over models can be tted with an optional humidication system in the form of a passive
water tray or an independently controlled boiler type system (which requires a permanent water
supply and drain).
