Block Ice Plants for Concrete Cooling
Development & Production
A team of qualified engineers, technicians and service engineers guarantees highest quality, reliability and service at any time.
With modern CAD-, planning- and production-systems, KTI is able to design and manufacture refrigeration plants in the shortest possible time.
Assembling and testing containerized refrigeration plants inside our manufacturing hall reduces installation and commissioning times on site, thus, minimizing risks and costs for our customers. By means of 2 heavy-duty cranes up to 4 containers can be installed on top of each other to pre-assemble complex refrigeration systems systems such as ice plants with ice storage containers underneath. On site, a water chiller can be started within hours, a few days are required
for an ice plant.
The idea of installing block and flake ice plants, chillers and ice storages inside of containers became so successful that more than 2000 plants could be sold all around the world during the last 20 years.
In 1994, it became necessary to move into new production facilities.
In 1999, due to the steadily increasing demand, the assembly hall had to be extended. After the movement of our office for administration and engineering to Unterbalzheim in 2002 we succeeded to double our production facilities until 2004.
The brine tank system
Thin-walled ice cans in specially designed racks are filled with precooled water and dipped into a tank where cold brine (salt solution) is circulated around the cans. After freezing, a row of cans is hoisted, moved to, and dipped into the harvest tank to loosen the blocks, then lifted and tipped out on an angled ramp.
The blocks slide out and are either stocked in a storage room or distributed directly as a whole block or in form of crushed ice.
Production capacities of 6, 8 10 or 12 t/d can be realised in mobile, packed containerized installations. The standard block size is 25 kg. Custom made sizes are available on request.
Ice storage
Air coolers and all around isolation of the container walls provide best conditions for ice storage.
Lifting & Transport system
A new kind of low-profile traveling crane has been developed for lifting, moving and tipping the ice cans.
High precision manufacturing techniques were applied in order to fit the crane to the inside of the containers. Rapid and precise operation of the hoist are facilitated by a 2-speed drive. Frame structure, reinforcement elements, winding drum and driving shafts are all made from stainless steel.
Interiors
The spacious interior of the containers, the installed air coolers and the checkered aluminium plates on the floor provide comfortable and safe working conditions.
Only minimum skills are required for standard operations, such as filling of the ice cans, ice-harvesting and ice-processing.
Materials & Components
Compressors
Reliable operation of the complex machinery layout is guaranteed by high-grade electrical switch- and control-boards. A full series of safety functions is implemented in order to protect the components of the installation by avoiding critical operation conditions.
Only high quality components and finest materials are used for the whole installation.
• Titanium Plate Heat Exchanger
• The brine tank is fully hot dipped galvanized, primed and finished with
special, high resistant epoxide-furnish.
• Brand new, CSC-certified, 40'- ISO-containers, painted white inside
and outside.
Outside dimensions (LxWxH):
12.192 mm x 2.438 mm x 2.896mm (40' x 8' x 9'6").
• Ice cans, racks, lifting hooks, hoist and water tanks, are from
stainless steel (1.4301/AISI 304 or 1.4571/AISI 316Ti).
• Robust compressors of the latest generation guarantee a maximum
of reliability.
• Evaporative condensers are used for low discharge pressure and
condensation temperatures.
• Under tropical conditions, the use of evaporative condensers is a
highly economic way to increase the energy efficiency and to
decrease the power consumption of the plant.
Refrigerant
The refrigerants used are worldwide accepted and go conform to national and international regulations.
Less refrigerant is required due to dryexpansion evaporation. This enables compact design of the insallation and contributes to troublefree and safe operation.
