In January 2025, a defense sector company from Eastern Ukraine announced a tender for the supply and installation of an industrial paint booth to service various types of automotive equipment. TWEKO participated in the tender and secured the contract. The project aimed to create a modern modular system for painting and drying, emphasizing rapid installation, energy efficiency, and explosion-proof safety. The solution’s unique feature is a quick-install modular booth with motorized roller shutters for optimized logistics, diesel heating, and a high-efficiency ventilation system (25,000 m³/h) with two-stage filtration (90–99%). The booth was tailored to the client’s foundation with precise pit geometry (730 mm). Explosion-proof components ensured safety, and efficient commissioning with staff training enabled project completion in a record 120 days, allowing the client to quickly launch operations and meet modern defense sector painting standards.

Project Objectives
- Design a paint and drying booth with internal dimensions of 7,120 × 5,580 × 3,750 mm for automotive equipment.
- Integrate a diesel-fueled heating system to maintain stable temperatures of 20–60°C.
- Provide supply and exhaust ventilation with a capacity of at least 25,000 m³/h and air purification of 90–99%.
- Install motorized roller shutters (4,200 × 3,600 mm) and personnel service doors with explosion-proof design per GOST 12.1.010-76.
- Develop a construction plan with pit geometry and dimensions for the foundation.
TWEKO’s Solution
TWEKO delivered a customized solution based on the AKFS Standard model KFS.000.00.00-ENERGY, series AKFS-S-7, tailored for automotive equipment. The project was completed turnkey, including sandwich panels, ventilation units, roller shutters, and a control panel.
Booth Structure:
- Frame-based structure with 60 mm sandwich panels (galvanized steel, mineral wool insulation).
- Overall dimensions: 7,120 × 5,580 × 3,750 mm.
- Work zone divided into two sections (4,590 mm each).
- Motorized roller shutters (4,200 × 3,600 mm) with reinforced sealing.
- Floor: concrete with filter pits, 30 mm high grilles.
- Service door: 1 unit, 800 mm wide.
- Ventilation units integrated on the booth’s side.
- Canopy with drainage system to protect the booth and ventilation equipment from weather conditions.
Robust construction and precise geometry ensure durability and rapid turnkey installation.
Thermal Ventilation System:
- Diesel burner heating via heat exchanger.
- Ventilation capacity: 25,000 m³/h with explosion-proof motors.
- Operating temperatures: painting 20–25°C, drying 40–60°C.
- Air ducts (18 units) with brackets.
- Chimney for exhaust gas removal.
Stable temperatures and high ventilation capacity ensure quality painting and fast drying.
Filtration System:
- Two-stage filtration system.
- Pre-filtration: 90–92% (pocket filters, 1,000 × 400 × 200 mm, 2 units).
- Main filtration: 99% (ceiling filters, 1,500 × 1,800 mm, 4 units).
- Additional cardboard and fiberglass filters for post-chamber cleaning.
Two-stage filtration ensures clean air, environmental compliance, and personnel safety.
Lighting and Safety:
- Explosion-proof LED T8 lights (1,200 mm, 4 × 18 W, 8 units) for illumination ≥800 lux.
- Automatic fire alarm system.
- Safety system with automatic air supply shutdown during power interruptions.
High illumination and comprehensive safety features ensure comfort and reliability.
Control System:
- Control panel (1 unit) for managing ventilation, temperature, and operating modes.
- Power: 14 kW.
- Voltage: 380 V, 50 Hz.
User-friendly control panel enables full management of painting and drying processes.
Project Implementation
The project was completed in 120 calendar days, from tender to final delivery. Key stages included:
Tender Request and Contract Award
TWEKO received the request and submitted a proposal for the tender. After a successful evaluation, a contract was signed for project execution.
Analysis and Design
Requirements for the foundation, gates, and ventilation were finalized. A construction plan with pit geometry was provided to the client, adjusted to structural specifications. Visualizations, air duct and chimney drawings, and technical specifications for a canopy with drainage were also prepared to protect equipment from weather conditions.
Equipment Manufacturing
The paint booth’s main components were designed and manufactured: frame, sandwich panels, roller shutters, ventilation units, and diesel heat exchanger. Laser cutting ensured high precision. A detailed assembly drawing with full specifications, including the canopy, was provided.
Installation and Commissioning
After foundation preparation, equipment was delivered to the site, where the installation team worked intensively. A canopy with drainage was installed to protect the booth and ventilation units from rain and other weather factors. Commissioning included filter installation, exhaust testing, and system activation. Coordinated efforts enabled completion ahead of schedule. The final stage involved providing the client with full technical documentation in English, including electrical schematics.
Results for the Client
- 120 calendar days from tender to completion — rapid project delivery despite foundation adjustments.
- Stable microclimate for painting equipment with 0.25 m/s air velocity and high purification (90–99%).
- Enhanced safety through explosion-proof components and automatic alarms.
- Optimized logistics with motorized roller shutters.
- Energy efficiency via diesel heating and well-designed ventilation.
