A Darlington-based manufacturer of cleaning equipment is expanding after recording a 315% growth in sales for its range of zero emission pressure washers.

MAC International, which is the UK’s largest independent manufacturer of bespoke static pressure washers and produces all of its machines at its North East headquarters, recently invested in the research and development of its MAC Zero Emission hot pressure washer range.

The business has responded to the growing demand by increasing its headcount in its marketing and production departments by eight. This strategic move is designed to support the accelerated growth of the Zero Emission Pressure Washer range throughout the UK and Europe.

MAC International managing director Simon Ruck said: “Electrically heated pressure washers never used to be particularly good or efficient, which is why people relied on traditional diesel heated machines, which emit CO2.

“A diesel-fired boiler produces approximately 2.6kg of CO2 for every litre of fuel burnt, which is around 18kg per hour of use.  This equates to a huge amount of CO2 emitted each year from these pressure washers, which we are committed to reducing and eliminating.

“This is why throughout the last four years we have invested in the research and development of our MAC Zero Emission hot pressure washer range, which requires no diesel to heat the water, completely removing fuel emissions entirely without compromising on quality or performance.”

“We have built a new manufacturing line in our Darlington factory. This has culminated in recruiting a new team of engineers and manufacturing staff to design and build our products here in the North East.

“We are confident that the growth of our business in the next 10 years will be centred around our world class emission free pressure washer range, as companies look for green, diesel free alternatives.”

Peter Gibson, the Member of Parliament for Darlington, met Simon Ruck to see the business’s new carbon neutral range, which now accounts for 40% of its total static hot pressure washer sales.

He said: “MAC International is a shining example of the investment that is going on and the manufacturing happening here in Darlington.

“It is important that we have companies creating emission-free carbon neutral products because as we go through the energy transition, consumers want to be addressing those issues.

“MAC International are really going places and it’s fantastic to see this investment and technology being delivered and manufactured right here in Darlington.”
