Conditioned air and cooling - Import export

Wide range capacity liquid cooled condensing units, designed for commercial and industrial applications with the cooling capacity from 10 kW to 40kW. These units work on a principle of the heat rejection loop, where condenser heat is dissipated to the environment via water. Rejected heat can be used for additional needs in the same building, which gives these facilities additional economic benefits. These units provide an economical, compact alternative to traditional air-cooled condensing units. Built on an open welded frame with standard profile, this condensing unit is also available in a double-deck construction for higher capacity. Assembled with shell and tube or plate heat exchanger, 1 to 4 scroll or reciprocating compressors and a liquid receiver as well as refrigerant filters and a sight glass. Safety valve and pressure switches are added to increase the security of the unit.

An indirect dry cooling system is characterized by the use of a condenser and air-cooled heat exchangers.The cooling system consists of the following main components :condenser (surface or spray type),cooling water circulating pumps and recovery turbines, if applicable,heat exchanger deltas including louvers,natural draft cooling tower,piping and valves,water storage tanks and transfer pumps,electrical equipment,instrumentation and control,accessories such as cleaning system, nitrogen blanketing system,The warm water from the condenser is delivered to the natural draft cooling tower by the cooling water circulating pumps and an underground piping network. After the cooling in the heat exchangers, the cold water returns to the condenser.

The RCDC ACC is designed with optimized key sections and equipment to guarantee a maximized efficiency. The steam flows from the turbine into a steam duct and several manifolds to reach the fin tube bundles. The RCDC ACC is designed in streets sitting on a steel leg system (under structure) raised to allow proper air intake into the forced draft modules of A-shape steelframes supporting the fin tube bundles. Once condensed the steam is collected by gravity into a condensate tank located underneath or in the close vicinity of the ACC. The efficiency of the steam condensation process is guaranteed using appropriate and reliable vacuum units. RCDC guarantee the complete system and undertake integral studies related to the ducts and manifolds, the steel leg system and the pipe work and other special studies as appropriate.

Full Automatic Ice Storage System ( Ice Rake Technology ). ROSEN Full Automatic Ice Rake Storages and Delivery System is the perfect combination with a Flake Ice Plants with this, certain amounts of ice can be stored over a period and discharged on demand and for covering demand peaks. An entire daily capacity of the ice plant can be discharged during the production in a short period. Even excess production capacity will fill the ice storage and is not lost.
