SAIVER Water Cooled Chillers are designed and constructed under the modular technology patent. A chiller bank consists of multiple individual chiller modules connected in parallel to operate as a single machine, with cooling or heating capacity to match the load demand by varying the number of operating modules. The chiller modules start from one module to fifteen for SMSW060 while the SMSW125/135 has a maximum of ten (VWF models has a minimum of four modules), giving you full flexibility to increase the capacity as your needs increase.

Each module contains a screw compressor, evaporator, condenser, and sophisticated control and protection equipments. Each module operates as a completely independent refrigeration circuit, and varying to the total load demand. The controller will change the chiller's capacity by either controlling the number of modules in operation or by adjusting the capacity of the last start up compressor.

The chiller is enclosed within an attractive but also sturdy frame and has removable doors for easy access and convenience for maintenance and service. The doors can be lined with acoustic insulation, which further silences the chiller. (optional)

Compact And Space-saving

The compact size of each module means easy access via standard doorways and lifts. You no longer need special access to install the chiller. In comparison to conventional water cooled chillers you can gain up to 40% more space. Meaning larger capacity chiller can be easily installed in confined and small places.

Add-on Flexibility

As your needs for cooling increases, SAIVER has the solution. Being a modular chiller, it has never been easier to expand the system as larger cooling capacity is needed to meet increased building load demands, with no complicated changes to the room, piping system or control system, and all work can be done quite easily.

Safe And Reliable

Every module works as an independent refrigeration circuit, with adjacent modules operating independently. In the event of a malfunction in the system, the computer selects the next available standby module to provide back up. One failed module will not disrupt the other chillers or system, giving you total piece of mind.

Peak Economy At All Loads

Automatic scheduling of the compressors allows the chiller to match the fluctuating cooling loads and conserve energy with each individual unit running at its peak efficiency. This is much more economical when compared to a large single unit running at part load.

Screw Compressor

Each module contains a high efficiency semi-hermetic screw compressor. The refrigerant drawn into the compressor flows evenly over the motor sealed inside the compressor case, and cools down the motor thoroughly. This ensures the motor is always working at the ideal temperature condition. The built-in protection part continually monitors the coil temperature via 6 PTC pre-fix in the coil. The compressor will shut down if abnormal temperature is detected.

The compressor has three stage capacity controls: 50%, 75%, 100%. This is accomplished through a slide valve regulating mechanism. Among all the compressors in operation, the last actuated compressor will run at a three stage capacity control mode to meet the load demand more precisely and keep the chiller running at peak efficiency.

There is also a built in pressure relief feature inside the compressor to by-pass pressure from the discharge to the pressure section whenever the discharge pressure is abnormal. This feature will protect the chiller from damage and prevent loss for refrigerant leakage.

Condenser And Evaporator

Condenser and evaporator use our brazed plate heat exchanger, which is manufactured from type 316 stainless steel, and able to withstand a working pressure of 2400 kPa and 2000 kPa for the refrigerant and water side respectively. The nominal chilled water flow through the heat exchanger is 5.6l/s at a maximum pressure drop of 43 kPa.

Internal Water Strainer

Internal water strainer is made from stainless steel. Internal water strainers are supplied and fixed inside both chilled water header pipes and condenser water header pipes for each module. It can be easily dismantled and removed. The internal water strainer can prevent particles contained in the water from getting into the heat exchanger.

Together with another patent product is a header pipe stub which connects to the end of the condenser pipe, which enables the user to flush, clean and drain to the condenser water system very conveniently.
