Finishing line with three paint booths and a drying tunnel
We built a finishing line for a Norwegian furniture manufacturer with three energy-efficient water-heated paint booths, each with autonomous control. The booths are based on a plate heat exchanger, and two of them are connected to a conveyor and drying tunnel. The entire equipment holds ATEX certifications and control is performed from a single touchscreen panel. A GRACO Merkur 30:1 finishing pump set and a G40 spray gun were installed at each booth.
The Project Challenge
The client needed a new finishing line for their industrial building that would accommodate three workstations and ensure energy-efficient and safe operation. Although the majority of the paint line was completely new, the conveyor had to be rebuilt from an existing system that was already in use.
How We Built the Solution
We built three paint booths based on plate heat exchangers, with water heating and autonomous control. The operation of each booth is monitored by a solvent sensor, and the loading of the filters is controlled by pressure differential monitoring, which signals in time when the filters need to be replaced. Two booths are connected to the conveyor and drying tunnel, while the third is standalone with a separate drying room.

Automation
All control takes place from a single touchscreen panel, where system parameters as well as trends from previous periods can be monitored. Safety is ensured by a freeze sensor and AT interlock.
Result
The client received an energy-efficient finishing line compliant with ATEX requirements, featuring three autonomous booths whose operation is conveniently managed from a single central panel. The new GRACO finishing technology enables flexible and fast work with various substances.

Manual finishing booths with drying tunnel and pump cabinets
For a returning customer, we manufactured wider manual finishing booths with a drying tunnel as well as specialized pump cabinets for paint pumps, into which safety leak trays were integrated. The solution was designed as a 3D model according to the customer's requirements, and in addition to the booths and pump cabinets, we organized all partition walls, doors, and finishing technology. The result was a fast and seamless implementation and a satisfied customer who received exactly the solution they wanted.
Manual finishing department: two paint booths and a drying tunnel
We established a dedicated manual finishing department for a long-term client to produce custom orders. We installed two 3-metre-wide finishing booths, six finishing pumps, a drying tunnel, and in-house manufactured GRINO drying trolleys. To ensure worker safety, we added barriers and fast-opening doors that separate the finishing area from the rest of production. The new department operates flawlessly and successfully fulfils all custom orders.
Renovation of a Door Manufacturer's Finishing Workshop – MAKOR Automatic Line and Manual Finishing Booth
An automatic finishing solution, MAKOR SPRAY & DRY – M, was designed and installed for a Central Estonian door manufacturer, together with a manual finishing booth built by Elister. The heart of the finishing process consisted of GRACO PerformAA automatic paint guns with Merkur-series pumps, and the ventilation was interfaced directly with the Makor system, which detects the operating equipment and adjusts the working modes. The entire system was designed, installed and commissioned into working order precisely during the factory's collective holiday, resulting in an energy-efficient and safe finishing environment.
