A sidecar unit that isolates the technology loop from facility water, holds supply temperature against a moving load, and keeps the fluid chemistry inside a volume you control. Redundant pumps run in a duty-standby arrangement with automatic changeover and equalised running hours.
Filtration, air separation, expansion and leak detection are inside the enclosure, so the room-side work is two pipes and a network connection. Control exposes supply temperature, differential pressure, flow and alarm state over Modbus TCP and SNMP.
