Paint Spray Booth Manufacturers in the UK
As leading paint spray booth manufacturers, we take an analytic approach to ensure our paint spray booths meet your production requirements. Our engineering and technology allow us to deliver high-quality, cost-effective paint spray booths that exceed your expectations. From open-fronted paint spray booths to enclosed designs, we offer solutions to fit all budgets, utilising state-of-the-art technology to reduce your energy bills.
The Problem With Traditional Paint Spray Booths
The majority of finishing plants that carry out pre-treatment and power stoving ovens are gas heated and the highest energy consuming part is the heating of pre-treatment tanks.
Here at PB Metal Finishing Engineers we have designed, manufactured and installed over 100 paint finishing plants. From our experience we know how much energy is required and wasted during the whole metal finishing process.
Our Spray Save Solution for Paint Spray Booths
We have developed a heat exchanger system that utilises the vacant space in ovens that isn’t being used. The contents of the pre-treatment tank solution are pumped from the tank through our Spray Save system heat exchanger and back into the tank.
The velocity of the solutions and the size of the Spray Save system are important and we have found that our system can achieve a high degree of heat transfer.
In the first system we installed we monitored the gas usage on the stoving oven before and after the installation and found no increase whatsoever in the gas levels for the oven. That first installation had no heating in their tanks at all!
Many systems we have installed surpass the estimated savings we suggest can be made.

How Our Paint Spray Booth Heat Exchanger Works
The Spray Save system comprises a fully valved and controlled, close-coupled pumping system complete with non-return valves.
Solution is taken at a low level from the tank thereby circulating the coldest area of the tank and also keeping the solution in movement. It is then pumped through the stainless steel schedule 10 fully welded and tested heat exchanger. The return of the solution is passed back to the process tank continuously.
The system has its own control stats and also interlocks with the main oven when firing. Normal practice is that the tank burner is switched on to power up the tank with the ovens being switched on at the same time.
Then at every pass of the heat exchanger the solution picks up excess heat and within a short period the exchanger takes over the heating process.
Normal run rates without the exchanger are approximately 6.5 hours per shift, this reduces to 1.5 hours per shift.
Therefore, if your tank burner is a 450 kW burner running on an 8-hour shift, costing £0.04p per kW of gas per hour, your savings per annum would amount to £21,000.00!
Advantages of PB Metal Finishing Paint Spray Booths
We don’t suggest removing the existing burners on the tanks as the initial heat-up using the burner and oven is quicker than just using the oven. However once heated to the required temperature, the rate of gas usage drops from 65% demand (of the max rate of the burner) down to 6%, thus providing an energy saving of 90% in gas costs!
Installation of Custom Paint Spray Booth Systems
Prior to installation we carry out a complete site survey for every client to determine the exact demands and size requirements. Upon completion an accurate, full quotation can be offered.
On average the payback is approximately 54 days, depending on the amount of hours run.
We design, manufacture and install all types of powder coating equipment tailored to your specific requirements. Should you be looking for a new system, we cannot recommend our Spray Save system enough to substantially lower the operating costs of your plant.
