Air cooled chillers

The ARA-T2 series air cooled chiller devices are units employing high efficient R410A cooling fluid with zero ozone thinning potential and having two scroll compressors. The device will start to run at half capacity in cases where the capacity need is low and the electricity consumption will be decreased significantly by being equipped with two compressors. Beside this, it operates at half capacity and the complete stoppage of the process is prevented in case of any defect of one of the compressors. The initial investment costs are low compared with fully independent devices. In addition, it has features like its capability to be installed rapidly and easily thanks to its high temperature sensitivity, optional colour touch-screen control panel, integrated module.

ERW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled units, using EC (Electronic Control) axial fans. This range includes a series of models with cooling capacities from 2.1 kWf up to 595 kWf. Three different versions are provided for different outlet fluid temperature ranges, agreed with the customer during the design phase. The entire range uses refrigerant with GWP 631.

RW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled: the only resource used is therefore electrical energy, a decisive advantage in contexts where it is advisable to save water (because of its cost or scarcity). The IP54-grade machine protection (against dust and other agents) facilitates their installation in outdoor environments, which is also possible at temperatures up to +40°C and above, at the customer’s request. RW ax liquid chillers from Frigofluid are suitable for achieving average fluid outlet temperatures (between +1°C and 20°C), with excellent control of the resources used for their operation.

Low outlet fluid temperatures (water or water and glycol, down to -8°C) characterize RW ax LT liquid chillers: air condensation ensures that they use are electrical energy, and not water, for their operation: a resource that is then optimized by the electronically controlled “brushless” type axial fans. Up to +40°C ambient temperature allowed in standard execution.

The secret of this system is the combination of the refrigeration section and the free-cooling section depending on the time of day and year: the first mode allowed by these liquid chillers takes advantage of the normal operation of a refrigeration circuit, the second allows cold outside air to be directly conveyed to the fluid to be cooled: maximum efficiency, minimum energy use due to the clear separation between the two sections.

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.
