Partial Frozen Design
The temperature of refrigerant solution rises when it flows through the coil during ice building cycle, so thicker ice is formed near the inlets of coil, and thinner ice formed near the outlets. Therefore, the final shape of ice tends to be tapered. If the coil is set in parallel circulating, the tapered ice can lead to wasted volume of storage tank. Runpaq solve this problem by the application of convectional flow circuits, the tapered ice cylinders nest with each other make efficient use of tank. Benefit is that the same amount of ice can be built with the convenctional refrigernat configuration as can be built with an ideally constant temperature directly evaporating refrigerant, where the cylindrical sections of ice would have no tapering. At the end of charging, the 0ºC water surround the tapered ice cylinders to the partial frozen condition. The partial frozen ice storage suitable for both internal and external melting system.

Counter-current flow circulating Tapered Ice Counter-Current Flow Circulating
Nano-composite Plastic Ice-on-coil
Runpaq patented Nano-composite polymer coil, has been successfully applied in ice storage as ice-on-coil. Taking advantage of melting intercalation technology, we directly intercalate the polymer matrix material into the thermal-conductive filler layer uniformly to form a thermal-conductive network.

The partial frozen internal-melting ice-on-coil steadily supplies 3-4ºC refrigerant during ice-melting cycle, thus reduce the capacity of other equipment and save the initial investment and operation cost.
The external-melting option has good ice-building performance and an air flow path to enhance ice-melting, hence maximally avail the space. The Runpaq ice-on-coil has 1.3 to 2 times heat exchange area by comparison to other similar products. and its fast melting performance can provide 1ºC or below cold water, makes it an ideal choice for district cooling system, or low temperature air supply system.

Optional ice sensor
It measures the ice volume, and transmit signal. Two types available: liquid level type and ice thickness type
1. Liquid level sensor:
Principle: the volume of ice is more than water under the same mass in view of the ice property: less density than water. Therefore, when the coil is charged by ice, the water level will rise up, so the risen height reflectsthe ice volume.
2. Ice thickness sensor
It works on base of the conductivity of ice and water difference.
