- Under the following conditions: Chilled water temp: 20 °C, ambient temp: 25 °C, at the maximum discharge pump circulating load. Cooling capacity is at least 95% of the noted figures. Heating capacity will change according to operating conditions.
- Source voltage phase unbalance should be less than ±3%.
- The figure noted is when operating at the highest capacity in the normal operating range.
- When the current load is continuously within ±10% and the ambient temperature is stable. However, this does not include starting times or when the heat-load exceeds the chiller capacity.
- Comes standard with a built-in overload protection circuit breaker (NFB).
- Operating noise levels are from a position of 1 m in front of the product and at a height of 1 m.
- The above prices do not include consumption tax.
- Note 1: The liquids (for chilled water) that can be used with this product are clean water or a 30 to 40% solution of industrial-use ethylene glycol. Alternatively, if conditioned water is used, then it should have an electrical conductivity of at least 1 μS/cm.
- Note 2: Heat output from the product (in kW) is approx. 1.3 times that of the cooling capacity.
- Note 3: Depending on the operating environment, situations such as condensation forming on piping inside the product or short-term leakage of leakage from the mechanical seals of the pump may occur. Please install a drain pan as needed in such cases.
