🚀 CoatTech Unveils CT-PQ-I-PLUS Series: Water Curtain Spray Booth & Curing Line for Premium Furniture Manufacturing

GUANGZHOU, CHINA — CoatTech Intelligent Equipment Co., Ltd., a global leader in intelligent surface coating and finishing solutions, officially announced the global release of its CT-PQ-I-PLUS Series. Designed specifically for high-end wooden furniture, cabinet, and architectural door manufacturers, the CT-PQ-I-PLUS integrates a heavy-duty SS304 Water Curtain Spray Booth with a precision Hot Air Drying Chamber, establishing a new benchmark for dust-free, export-grade liquid finishing.

🌟 Rethinking Wood Finishing: Zero-Dust, High Efficiency & Energy Savings

As global furniture markets demand flawless finishes—especially with complex PU, Acrylic, and Eco-Friendly Water-Based Coatings—traditional spray setups struggle with overspray handling and thermal inefficiency. The CT-PQ-I-PLUS is engineered to resolve these challenges through custom-designed airflow dynamic architecture and high-efficiency filtration systems.

⚙️ Core Technical Innovations of CT-PQ-I-PLUS

1. Heavy-Duty SS304 Water Curtain & Multi-Stage Scrubber

Corrosion-Free Construction: The 3,000 mm wide water curtain is manufactured entirely from 1.5 mm Grade 304 Stainless Steel, eliminating rust and corrosion risks associated with water-based finishes.

>95% Overspray Capture Rate: Equipped with an explosion-proof vertical inline pump (20 m³/h capacity) creating a continuous water wall, combined with multi-tier air filtration (G3 intake pre-filter + F5 full-depth ceiling sticky tack filter).

2. High-Speed Hot Air Curing Chamber (20°C to 70°C in 10 Mins)

Riello Italian Diesel Burner: Paired with an AISI 304 Stainless Steel heat exchanger, delivering rapid heating from 20°C to 70°C in just 10–15 minutes.

Uniform Thermal Distribution: High-volume centrifugal recirculation fans (10,000 m³/h, 100 air changes/hour) maintain a strict temperature uniformity of ±3°C, preventing thermal cracking on solid wood and MDF doors.

3. Industry 4.0 Smart Automation & Safety

Siemensbrand & ABB Architecture: Controlled by a Siemensbrand PLC + Touchscreen HMI paired with ABB Variable Frequency Drives (VFDs) for all motors.

Mandatory Safety Interlock: Features a smart interlock system requiring water pump activation prior to paint spraying, protecting workers and reducing equipment wear.

Conveyor Rail Ready: Pre-engineered with top door track cutouts to seamlessly integrate with overhead or floor conveyor systems.

Global Success Story: Empowering MENA's Leading Furniture Exporter

The launching of the CT-PQ-I-PLUS series comes on the heels of a successful custom deployment for I Furniture Group, a major furniture exporter based in Alexandria, Egypt.

[ Raw Wood / Doors ] ➔ [ 1. Water Curtain Spray Station ] ➔ [ 2. Flash-Off Zone ] ➔ [ 3. Hot Air Curing Chamber ] ➔ [ Export Finish ]

Client Challenge: The client needed to upgrade their production line to produce export-grade wooden doors and furniture using PU and water-based paints. They required a dust-free environment while keeping local energy consumption costs under control in North Africa.

CoatTech's Solution: CoatTech engineered a 3-chamber modular layout (total footprint: 12.2m x 7.3m) with individual booth clear working dimensions of 6000 x 4000 x 2800 mm. By recommending a diesel-fuel burner instead of electric heating, CoatTech reduced the client's thermal energy running costs by over 40%.

Result: The facility achieved complete compliance with European export surface finishing standards, zero dust contamination, and reduced overall drying lead times.

📋 Comprehensive Technical Specifications

For engineering evaluation and technical comparison, the core parameters of the CoatTech CT-PQ-I-PLUS line are detailed below:

Q1: What makes a water curtain spray booth better for wood furniture than a dry filter booth?

Answer: Water curtain spray booths utilize a continuous film of flowing water (made of AISI 304 stainless steel in CoatTech's system) to trap sticky overspray from PU, water-based, and acrylic paints before it reaches exhaust fans. This eliminates filter clogging, maintains stable air extraction velocity, and significantly reduces operational maintenance costs in high-volume wood furniture lines.

Q2: Why is diesel/gas heating recommended over electric heating for industrial drying booths in MENA and overseas markets?

Answer: Industrial drying booths require rapid thermal ramp-up (e.g., reaching 70°C in 10 minutes). In regions like North Africa and the Middle East, electricity tariffs for high-kilowatt heating elements are significantly higher than gas or diesel fuel costs. Utilizing a fuel burner (such as an Italian Riello burner) cuts energy operational expenses by up to 35%–50% while providing faster response times.

Q3: Can the CoatTech CT-PQ-I-PLUS system be customized for overhead track conveyor lines?

Answer: Yes. The main entrance and internal doors of the CT-PQ-I-PLUS series come factory-engineered with top door header slots, allowing seamless integration with manual or automated overhead monorail conveyor systems for continuous workpiece transport.
