ALSIUS:
Marine HVAC and Refrigeration Technology for all kind of ships

Robust, durable, very efficient and easy to maintain ALSIUS components for air conditioning and refrigeration systems form the ideal base for maximum comfort and cost effectiveness in commercial shipping and on mega yachts.

Especially made up of an industrial standard for utmost safety and reliability, equipped with all safety devices and combined with environmental friendly refrigerants ALSIUS air conditioning and refrigeration systems within their power range set a new standard for highest demands.

Product Program – Air Conditioning

In order to offer a complete system for heating, ventilation and cooling purposes within a capacity range from 25 to 2,000 kW, ALSIUS product program comprises water chillers and condensing units as well as central air handling units and special fan coils.

The refrigeration plants for air conditioning of accommodation, control rooms etc. can be delivered either as direct expansion systems or as water chiller units for indirect cooling.

According to the required capacity or specific demands, plants can be delivered with reciprocating or screw type compressors. As standard all components of refrigeration plants are assembled as a compact unit mounted on a common base frame.

In order to provide highest safety and reliability ALSIUS water chillers are equipped with all necessary safety devices and can also also be offered as DNV GL certified units. Only components of well known suppliers and grade one quality are accepted.

With the selection of refrigerants HEFKO Products counts on environmental-friendliness and cost-effectiveness. Alternatively R134a, R410A, R404A or R407C are used. In any case can be assured, that all refrigeration systems on board operate with the same refrigerant and therefore operating cost are low.

The heat exchangers of condensing units and water chillers for marine applications are of special shell and tube type design, developed and constructed for sea water cooling and reliable operation under typical ship movements rolling and pitching. Their use offers a very compact design in line with the space available in machinery rooms.

Product Program – Provision Cooling

ALSIUS refrigeration plants for cold stores are available as standard split systems or as custom made plants with sea water cooled condensing unit and air coolers forming a total package with necessary operation and safety system. Condensing units can also be delivered as central cooling/freezing machinery for refrigerators and catering equipment.
