Hi-Tec Spray drives up pressure

21 April 2010

Several years past Hi-Tec Spray Ltd. (HSL) designed and commissioned their very first Mobile Rig that incorporated the use of the Graco A-20 Reactor from their range of Plural Component Proportioners.

Reactors are used for industry-wide applications of fast setting materials – including polyureas and foams. The A-20 is only one of an extensive range of machines but has become the industry machine of choice for the application of polyurethane fast setting insulation foam.

The rigging out of vehicles has since evolved into a major component of HSL’s business development, especially as the procedure from the customers’ standpoint is less than complicated; the customer supplies the vehicle and HSL do the rest.  Within 2-3 weeks a fully equipped, pre-commissioned vehicle is presented with free training and an additional visit by an engineer to assist with initial start-up on site within the UK.

The mobile rigs now have a significant presence on construction sites around the country as well as being the standard outfit adopted by the insulation contractor operating in the domestic roof insulation retrofit industry.

The purpose of the specific equipment within each vehicle is to address every aspect of application –  hot or cold application, large or small volume and low level or high rise environment and to achieve that the installed kit comprises of:

•    Graco A-20 Reactor, with integral material heaters; built in automatic shutdown facility to prevent off ratio spraying and user friendly control panel.
•    Fully heated hose bundle to deliver the materials to the spray gun at a constant controlled temperature.
•    Minimum hose length is 18m (60ft) and maximum is 64m (210ft).
•     Graco Fusion air purge spray gun with mixing chamber and air cap.
•    Graco Husky air operated diaphragm feed pumps to deliver the ‘A’ and ‘B’ materials from on board 200 litre drums to the Reactor.
•    The proven, petrol powered, 7.5 HP belt driven ABAC air compressor together with all interconnecting hoses and support bracketry complete the installation.
•    The system is supplied for 240 volt operation or can be specified for 415 volt 3 phase electrical supply.

All put together at a very competitive price that minimises the contractors’ capital outlay.

Hi-Tec Spray Ltd. supply more than applications equipment and plant in isolation.  They also develop a partnership with their clients to design and develop turnkey systems, where, on the one hand – individual components work well independently and on the other – collectively fit together like a glove.  They are probably the only company able to pull both sides of the industry together to deliver that total professional solution.
