Leak monitoring upgrade for AquaSnap chillers


17 June 2019
Carrier has upgraded its AquaSnap 30RBMP-30RQMP chillers with built-in connectivity for fixed refrigerant leak monitoring and the addition of its Touch Pilot control system.

The manufacturer says the changes make the chiller easier for end users and maintenance contractors to operate and helps to reduce the cost of ongoing maintenance by automating checks required under F-Gas regulations. 
A compatible fixed refrigerant leak detection system can now be connected directly to the chiller, linked to the chiller’s own control system. This speeds up customer or contractor notification in the unlikely event of refrigerant loss and enables more timely corrective action to be taken.

Carrier can supply and fit compatible refrigerant leak detectors, which includes all wiring connections between the sensors and the chiller control panel.

Use of a fixed refrigerant leak detection system reduces the number of mandatory site visits required for testing the chiller under F-Gas regulations by half, saving the end user significant costs over the lifetime of the chiller.

The upgrade also includes replacement of Carrier’s Prodialog+ control system with the Touch Pilot system. The new control system offers alarm notification by email and SMS alert for rapid response and facilitates easy connection to Building Management Systems. Performance data stored within the unit’s onboard memory can be analysed via a user-friendly graphical display, which shows trend data over time at the touch of a button.

A “black box” stores all operating parameters for 15 minutes leading up to an alarm or failure, making it possible for Carrier’s service team to assess the cause of a problem and ensure the root cause is identified and rectified.

The Touch Pilot also features an F-Gas leak check alert that enables a reminder to be programmed to help ensure mandatory leakage inspections are not missed. The reminder message remains on the chiller’s control screen until reset by the maintenance operator. If the inspection date expires without being addressed, an alarm is activated until the issue is resolved. This helps to ensure mandatory inspections are not missed and the unit remains compliant with F-Gas legal requirements.

The upgrade option is now available on all new orders of the AquaSnap 30RBMP-30RQMP chiller range, which is available in cooling capacities from 160kW to 510kW.
