4 Service Types

Maintenance Contract

We offer a comprehensive nationwide maintenance service.
There are four types of maintenance contract we offer to cater for a wide range of needs and we provide detailed records and reports for all maintained equipment.

Emergency Service

4Service provides 24 hour / 365 day cover for all contracted customers with guaranteed response times. Comprehensive geographical coverage and emergency escalation infrastructure ensures that in the event of critical breakdown all eventualities can be accommodated. Our Engineers carry a range of frontline spares, with round the clock access to our central stores facility for additional support. We take pride on being able to offer our customers a level of support that ensures fast and efficient turnaround of all emergency breakdown situations.

Full System Commissioning

Time pressures during construction often mean that building services systems are not properly commissioned and so never give optimum performance. The best option is to engage 4Service to commission your system at the outset. Alternatively, we can carry out retrospective commissioning. The result will be a plant that operates to design specification and is fully able to meet the demands of the end user.

Checking of energy efficiency

Our specialists and experts – not only from the areas of refrigeration technology and refrigeration, but also from the field of building equipment – perform energy audits at individual facilities, and inspections within the context of the German Ordinance for Energy Saving (EnEV) and of DIN V 18599.

These inspections include measures for testing of components that influence the efficiency of equipment facilities – and for checking the dimensioning of these facilities with reference to the cooling demand of the building. The inspections especially entail the checking and evaluation of influences that are relevant for design of the equipment, especially changes in space utilization and occupation, times of use, internal heat sources, the relevant physical properties of the building, as well as the desired values requested by the user with respect to air volumes, temperature, relative humidity, operational periods, as well as tolerances – including determination of the efficiency of essential components.
