SERVICE AND MAINTENANCE
HVAC assets: AHUs, chillers, heat pumps, condensers, energy management systems but also water quality and peripheral devices such as grilles and louvres are a substantial investment. Longevity of products can only be achieved through a planned approach to their overall maintenance. Aside from the long-term
mission critical applications such as data centres or hospital environments heating and cooling are fundamental.
Cooling It is imperative that chillers and air handling units are not
maintained to avoid equipment failure. PPM plans can mitigate
As a mission critical infrastructure, data centres are reliant on
reliable sources of power – consistent access to the national grid with equipment able to handle any interruptions to power and water. Uninterrupted power supplies may comprise generators, batteries, and related switching equipment, however any built-in redundancy can be negated if due diligence is not deployed, and equipment is not regularly monitored and tested. aspect of the HVAC system to be covered. Depending on the application, FMs may follow scheduled maintenance - covering issues before they become a fundamental problem. Predictive maintenance strategies may use smart tools enabling FMs to gather and monitor data from various points of and enable informed decisions to be made. a judgement on the condition of chillers or AHUs and the expected to operate the same, but when running several estates identical and other factors may come into play which may alter operation and performance.

require adaption, enhancements, or new installations. A PPM is the strongest line of defence and can pay for itself. A good PPM enables FMs to reduce reactive maintenance and ensure that assets are maintained to the required level. Realistically though, maintenance is not always ‘preventative.’ Certain conditions may necessitate a total replacement, which is not ‘preventative’ at all. up to 20% more electricity. plans for each piece of equipment, air conditioning and chiller inspection reports and an inventory of refrigerants can also provide information on your plant’s capacity and the areas it serves.

This in turn will help FMs to develop an energy savings

systems run continuously and using amounts of potable water and energy.
