“We removed the automation, so these systems are manually operated, with cat and mouse and ultrasonic level indication. The de-icer systems are operated by the Airport Fire Service, so the specification was changed to minimise any possibility of damage or future repairs. Simon Hewitt, MD at Chem Resist comments, “Word of the De-Icer Systems had spread within the HIAL Group, so we next won the project to work with Wick, but their requirement was different, so we developed a simplified system for the smaller airports and those located on the more remote islands. The project at Inverness was completed in October 2012. The project at Inverness was a large capacity system of 180m 3 which was automated using a control panel to fill the agricultural long-armed spray vehicle with the exact amount of de-icer needed for the runway. The pipework and every component including the valves, seals and ‘O’-rings need to be operational at these low temperatures due to the critical nature of the application.Ī Chem Resist De-Icer Storage System project for BAA at Glasgow Airport, completed in November 2011, led to a project at HIAL’s Inverness Airport. Using metal storage tanks in these conditions would see them quickly corrode.Ĭhem Resist specialise in Thermoplastics, so the material of construction is proven down to -40☌, but the whole de-icer storage system needs to be ice-proofed.
The challenge really comes from the local weather conditions which can include snow, rain, high winds and temperatures as low as -20☌. ECO-GEN is aqueous potassium-based solution which is not particularly aggressive so won’t damage the aircraft, engines and parts as a salt-based version would. CHEM RESIST EXPERIENCEįor the planes to operate, the runways need to be free from ice salt-based de-icers cannot be used so ECO-GEN runway de-icer is used instead.
The airports not only enable connections for people and goods but support critical services such as Emergency NHS passenger transfers, Royal Mail services and the offshore energy industry. Some of these have limited access to surface alternatives and the region’s weather can also mean that ferry services can be disrupted by high winds and rough seas. These connections support economic and social activities by enabling lifeline services to locations with populations from 5,000 people to fewer than 600. With its head office in Inverness, the private limited company is subsidised by the Scottish Government and sponsored by Transport for Scotland. Highlands and Islands Airports Limited (HIAL) operate 11 airports across the Scottish Mainland, the Islands of Orkney and Shetland and the Inner and Outer Hebrides.
