Advanced Engineering’s new improved SmellyJelly formula means clean fresh scents linger much, much longer.

SmellyJellies, the fragranced gel blocks for air con systems, now have a new formula with a more powerful performance and a much longer-lasting effect.

With the help of scientists at the University of Surrey’s world-renowned chemistry department, Advanced Engineering’s SmellyJelly products have been reformulated to survive at even higher temperatures of up to 70°C.

So once they’re in place after a HVAC service, SmellyJellies endure for a more sustained period of time, release more fresh fragrance and are even more effective at delivering that all-important ‘just-cleaned’ smell that gives your clients tangible evidence of a job well done.

Whether you choose Citrus, Floral, Mountain Fresh, Morning or a mixed pack all you need to do is open the filter and place a SmellyJelly gel block as close to the discharge point as possible, allowing the air flowing out of the unit to blow across the gel.

Both the large size SmellyJelly (designed for large fan coil and cassette units) and the smaller SmellyJelly Mini (for smaller fan coil units) have been enhanced.

Advanced Engineering has also just added a new ‘apple’ scent to the range, replacing the now retired ‘herbal’ fragrance.
