Product features
Capacity Control
- Capacity control function STEP BY STEP or INVERTER CONTROL
- Starting and stopping the compressor less frequently allows long term operation.
(No material fatigue caused by vibration during start and stop operations.) - Decreased power cost through start and stop operations.
Medium Circulation Pump (Optional)
- Designed to match load resistance. (Option)
- Adopted inverter to release air in plumbing after the mold has been replaced for maintenance work. (Option)
- Hot runner temperature maintained inside the mold when operation of the load is stopped (For flow control) (Option)
Customized Specification
Saturated steam is used for the heating source.
Suction head of the refrigerant pump.

Refrigerant
R410A (Substitution of Freon)
The ODP (Ozone Depletion Potential) of this refrigerant is zero.
DI water unit (Optional)
Countermeasures for scale adherence.
Maintains the electric conductivity of the system and medium water in the load to 0.1 mS/m (1 uS/cm).
Monitor function.
The electric conductivity meter displays the conductivity of the water medium.
Install the DI water unit inside the system for new installation.
Install the unit at the side of the system for installation to pre-installed systems.
