InoacWe are pleased to to advise that Inoac is now available in White. The market leader in trunking and fittings, Inoac is now available in both ivory and white. Competitively priced and produced to the highest of standards, this top quality versatile range of PVC trunking is designed to hide unsightly pipework in air conditioning, refrigeration and heating applications. It is aesthetically pleasing and will blend in with an assortment of environments, being suitable for both internal and external applications.

Not only has it become the preferred choice for installers and specifiers within the HVAC industry, but it is quickly becoming recognised as the superior alternative to the conduit that electricians and electrical contractors use.  The trunking comes in 2 metre lengths and is available in four sizes (60mm, 75mm, 100mm & 140mm). There are a comprehensive range of fittings available so it is no wonder that this flexible product has become the discerning engineers choice - creating the perfect solution to complete a smart installation where sub standard 'economy' trunking is not acceptable.

With the most popular colour being ivory, a white alternative is now available. Substantial stocks of Inoac are held in the UK and are readily available from all good wholesalers, Nationwide.

Marstair Refrigeration Condensing Units now ECA approved!

Marstair, a division of TEV Ltd., have just announced that with effect from the 1st October their MRC+ range of 13 units from size 50 to 180 have been added to the Energy Technology List and as such are eligible for the Government's Enhanced Capital Allowance.

MRC+The Enhanced Capital Allowance (ECA) scheme will provide 100% tax relief for the MRC+ Refrigeration Condensing Unit product range, in the same tax year as the purchase is made. As well as the added tax incentive, investing in the MRC+ product range could reduce a company's energy bills. A further benefit still would be the reduction in a company's Climate Change Levy, thus providing significant long-term savings from the initial investment in the product.

Chris Chisman, Marstair's Operations Manager explained that "customers would now be able to benefit from all the design work carried out by our engineers to make sure our products are some of the most efficient in the market".

If you would like further information about the MRC+ range please call Heronhill on 01823 665660 or visit
