Lineo extractor fans by Vortice ideal for easy commercial maintenance
The Lineo commercial extractor fan has been applauded by Vortice customers for its ease of maintenance. This in line mixed flow duct fan is designed primarily for commercial use, although the smallest model in the range, Lineo 100, can also be used for domestic bathrooms. Its key benefit is that the main body of the fan can be removed without moving or changing the ducting that’s already in situ. Lineo is ideal for duct-mounted ventilation requiring good pressure, high air flow and low noise levels.
Lineo is produced in self-
extinguishing V0 plastic and can be used with a selection of environmental sensors like Humidity, PIR, Smoke, Timer and Temp. Timer models are adjustable from three to twenty minutes and all models can be used with a telescopic wall liner and louvered external grille or fixed grille. Technical Manager Ian Davis said: “Lineo is not a new Vortice model, but it certainly is a stalwart. Customers love it for commercial applications because it’s so easy to maintain. It has long life ball
bearing motors which
are guaranteed for 30,000 hours continuous, trouble free operation.” For further information about Lineo and other Vortice products visit

Fire in hospital air conditioning chiller sparks warning over plant maintenance
A fire in an air conditioning chiller at a London hospital has highlighted the importance of ensuring regular maintenance of building services plant, particularly in the light of anticipated future cuts in public spending. The water-cooled screw chiller was

serving critical areas such as operating theatres in the hospital, as well as providing comfort cooling for patients and staff.
The fire broke out in the chiller’s control enclosure, destroying a section of the system and putting the air conditioning plant out of action. LH Plc, the Wimbledon-based chiller and air conditioning specialist, was called in to investigate the cause and repair the chiller. The company’s Andy Boatwright said: “Fortunately, the fire was contained and localised, and didn’t spread beyond the chiller plant, but it could have been extremely serious.” He added: “It illustrates the importance of ensuring regular maintenance, particularly in relation to equipment that serves critical or high value areas, such as hospitals, financial dealing rooms or computer centres – where it is not just people’s comfort that is at stake if the system goes down.” Chillers should be regularly serviced and maintained, he says, to avoid such problems and ensure they are operating efficiently. LH uses a thermal imaging camera as part of

chiller maintenance to identify “hot- spots” in plant that may indicate problems that, if left untreated, could lead to future breakdown.
“It is particularly useful for picking up problems in electrical and control systems, as faults often result in arcing and heat generation – which shows up vividly as colour flares via the infra-red survey. It would certainly have picked up the problem that led to the fire in the hospital chiller.”
LH recently launched a Chiller Health Check service, which uses infra-red imaging and a new performance analyser called Climacheck.
A test takes about an hour, and can spot problems such as control faults, refrigerant loss and compressor wear or damage, causing serious
underperformance and possible chiller failure in future.
“It could save the end user literally thousands of pounds in reduced energy bills and dramatically improve the performance of a building’s air conditioning,” says Mr Boatwright. “It can also spot major trouble spots before they lead to breakdown.”
He adds: “In the majority of cases, we can guarantee lower running costs, reduced carbon emissions and a cooler, more productive and safer working environment for building occupants.” For more details, contact LH on 020 8947 0886;
