Ice Banks

Application areas :
Ice banks are used in all areas of technology, e.g., in the classic area of refrigeration
engineering, but also in canteen systems and in climatization engineering. The ice bank technology can be used for a large portion of manufacturing plants, their use also enabling financial savings. The construction of the ice banks was carried out with consideration of the most up-to-date production methods, whereby the models are completely made of stainless steel. The containers have a double, diffusion tight insulation made of environmentally friendly materials. The entire, very robust construction offers great advantages for the export sector.

Low maintenance
Flexible adaptation or dimension
Connections based on customer specifications
Water circulation with stirrers or air injection

=======================================================

Evaporator
Stainless steel evaporators are successfully used in the refrigeration, manufacturing and in the general plant sectors. One can select between plate and pipe coil evaporators. It features comfortable clean ability and a minimum amount of content for all refrigerants.

The exchange surface can be used optimally in each application. Along with the optimal solution for almost all tasks, the variable welded construction in this heat exchanger also provides the additional advantage of highpressure ranges.

Application areas
Biotechnical systems
Chemical apparatus engineering
Ice bank systems
Trickle or film apparatus engineering
Heating or cooling zones and floors
Heat reclamation systems
Cryo engineering
Gas liquefaction

Product features :
Compact and solid construction
Best possible heat transfer
Simple cleaning of plate systems
Flexible design
High-quality workmanship
Long service life
Low volumes in plate desings
Low pressure drop in plate designs
Volume dependent manufacturing in the plate systems

=======================================================

Wine Cooling-Plates

Our wine cooling-plates are manufactured using the electric resistance process, ensuring an extremely smooth plate. They prevent deposits and germination thereby eliminating the possibility of bacterial formation. With their polished surfaces, the cleaning process is quick and thorough leaving no residue.

A wellcoordinated product range facilitates simple selection of the cooling plates needed.

Application areas :
Wine cellar engineering
Wine production
Tank construction
Chemical and food grade sector
Industrial plant engineering

Product Features :
Extremely smooth surfaces
Threaded connections with orbital welding
Highest rate of heat transfer
Guided water flow in the plates
Easy to clean
Perfect workmanship
Long service life
Standard range of products
Volume dependent manufacture

=======================================================

Trickle cooler / crushed icemaker

Trickel coolers have been used for many years.
In recent times, when the manufacture of heatexchangers has been rationalized, this type of refrigeration is finding increasing use. The outstanding advantage is that the water distribution is handled by an ingenious system. When compared to distribution using a punched trough, this design has the advantage of non soiling thereby ensuring uniform distribution of the fluids to be cooled.

The trickle cooler is made totally out of stainless steel and has an insulated colleting reservoir.
Furthermore, our drip coolers excel because during the flooding operation the boiling retardation is low, whereby overheating can be selected during the dry expansion operation. Our trickle coolers are currently used in most industries including the food, dairy and chemical industries, airconditioning, meat processing, heat pumps, artificial snow production

Application areas :
Food industry
Dairy industry
Air conditioning technology
Crushed ice production
Meat processing
Heat pumps
Artificial snow production
Chemistry
Soiled media

Product features :
Compact and solid construction
Fastest possible cool-down
Highest profitability
Food grade materials
Low maintenance
Simple cleaning
Flexible design
Adaptation to the body
High-quality workmanship

=======================================================

High Pressure Heat Exchangers - Coaxial

Coaxial heat exchangers offer a special solution for all industrial manufacturing processes involving cold and heat reclamation plants.

Above all, in systems where the fastest possible heat exchange is required, the counter-current model ensures a high level of efficiency. The coaxial heat exchanger consists of two pipe coils conducted through each other, which are wound into a snail form. The primary medium runs in the counter-current to the secondary medium in the pipe interspace.

Application areas :
Heat pumps
Cooling and air-conditioning systems
Heat reclamation
Climatic cabinets
Tempering devices
General manufacturing processes

Product Features :
Compact and solid construction
Best possible heat transfer
Highly efficient
First class workmanship
Long service life
Largest exchange area with small space requirements
Standard program for liquefiers and evaporator functions

=======================================================

Sealed plate heat exchanger RED-MATIK

The RED-MATIK is basically constructed of one frame on which individual plates are stacked. The frame consists of one robust plate to which the bolting and opponent plate is attached. Each individual plate is notched on the upper and lower side offering a precise positioning of the sealed plates by the bolting. The dimensional accuracy of each component offers best heat exchange. Easy disassembling and thus easy maintenance or increase of number of plates.
A medium combination of liquid/liquid, gas/gas or gas/liquid is possible. Also a great variety of materials, thicknesses and complementary components are available.

Application areas :
Heating
Cooling
Condensation
Vaporisation
Pasteurization
Heat recovery
