Air Cooled Chiller Planned Maintenance

An air cooled chiller planned maintenance visit for a long standing customer of ours. They have just signed up to another 3 year contract. We know at Maximus Chillers that if we want to keep our customers, we must continue to offer the Maximus Service. Maximus is Latin for the highest and the greatest

Planned Maintenance for Air Cooled Chillers

Planned maintenance is essential for these air cooled chillers as they are critical plant. They feed a large conference room which is a major part of the end user’s business. They can’t afford to loose the conference room when there is an event on. There is redundancy in the plant, but the customer always makes sure that the issues highlighted on the planned maintenance are acted on promptly. Also, the chillers feed a water cooled condenser for a pack which cools £50,000 of products used during the conferences

Air Cooled Chiller Oil Planned Maintenance

1mw of cooling across 2 air cooled chillers were undergoing planned maintenance. Our engineer noticed that the oil level was slightly below the sight glass on one of the 250kw Bitzer compressors. The machine had previously been extensively run tested to ensure no oil return issues were present. Therefore, he decided to adjust the level with the oil available onsite

Economiser

The economisers, in the picture, were tested to ensure the solenoids were opening when the program sent the run signal. The electronic expansion valves functioned correctly and subcooled the liquid further after the condenser

Head Pressure Control

The head pressure control was functioning correctly, keeping a steady 8 bar of pressure across all stages of loading and water system temperatures. This is because these chillers use a fan speed controller for each system. The fans cut in at the minimum running speed, which prevents stalling and over heating. Also, all fans running together are more reliable. Fans fail on systems using relays or pressure switches as the higher pressure fans don’t often come on. When they do, moisture has ingressed into them causing them to fail

Air Cooled Chiller Maintenance Bodger Watch

We carry out air cooled chiller maintenance at an office building in the North West. Chiller maintenance is usually very good, but this is bodger watch! The customer told us that there had been this guy who used to come who spent most of his time in the canteen- reading manuals on his laptop! Not even the manuals for that site either! You couldn't make it up could you? What kind of a chiller maintenance schedule is that? They said he used to fix everyone's bathrooms in the evening to make up his pay! This is bodger watch!

Air Cooled Chiller Maintenance

One of our engineers rang the office from a site we look after the other week. He was struggling to carry out the maintenance- the antifreeze dosing. He was advised to use his testing instrument to assess the level in the water system. He came back with the result- too much antifreeze. The customer uses propylene even though the site is heavy industrial. This is because the price is narrowing between propylene and ethylene and propylene is not toxic

On Site Maintenance Engineer

The customer adding antifreeze is the usual course- it means their onsite engineer can keep on top of things. This onsite engineer was a little too keen though: he had been putting too much in

Antifreeze Removal

Our pump out team was sent to site with their tanker and equipment. Then, the correct level of antifreeze was then charged into the system

Clear Site

Last but not least, our engineer gave the machine a wipe down and the chiller location a sweep- good house husbandry costs nothing
