Additional services

Oil analysis

Trane Oil Analysis is a predictive tool used to detect 
minor issues before they become major problems. It also 
reduces failure detection time and allows planning for 
appropriate maintenance. Oil changes can be reduced 
by half resulting in lower operating costs and a lower 
impact on the environment.

Vibration analysis

Vibration analysis is required when oil analysis reveals 
the presence of wear indicating the start of possible 
bearing or motor failure. Trane oil analysis has the ability 
to identify the type of metallic particles in the oil which, 
when combined with the vibration analysis, will clearly 
point out the failing components.

Vibration analysis should be performed on a regular 
basis to build a vibration trend of the equipment and 
avoid unplanned downtime and costs.

Compressor R’newal

To ensure a long lifetime for Trane compressors, system 
oil and vibration are regularly analyzed. These tests build 
a detailed picture of the condition of internal system 
components. Over time, they also help build a `wear 
trend’ of the equipment. This informs our service experts 
whether your compressor is due for minor maintenance 
or a complete overhaul.

System upgrade

This Service provides a consulting service.

Upgrading your equipment will increase the unit 
reliability and can reduce the operating costs 
by optimizing the controls A list of solutions / 
recommendations to the system will be explained to the 
customer Actual upgrade for the system will be costed 
separately.

Water treatment

This Service provides all of the necessary chemicals 
to properly treat each water system for the period 
designated.

The inspections will be conducted at agreed upon 
intervals and Trane Service First will submit a written 
report to the customer after each inspection.

These reports will indicate any corrosion, scaling, and 
alga growth in the system.

Refrigerant analysis

This Service includes a thorough analysis for 
contamination and solution upgrade.

It is recommended that this analysis be performed every 
six months.

Annual cooling tower maintenance

This Service includes the inspection and maintenance of 
the cooling tower at least once a year.

This involves checking the motor.

24 hours duty

This service includes emergency calls outside of the 
office normal working hours.

This Service is only available with a Maintenance

offer four different levels of coverage. From preventive 
maintenance plans to fully comprehensive solutions, you 
have the option of selecting the coverage that best suits 
your requirements.

5 years motor-compressor warranty

This Service will provide a 5 years part and labor 
warranty for the motor compressor only.

This Service is only available for units covered by a 
5 years Maintenance Contract.
