Mat Spray System

"Superior control, every spray." Designed for precise, repeatable application in front of the press.

Key Features

Telescopic boom — multiple spray heads off a single pump, individually controlled with master/slave selection
Automatic height control for optimal spray distance at all times
Unique safety boom — shields each NelJet® applicator, standard on all Mat Spray systems
Fully enclosed SS pump station with Grundfos DDA dosing pumps — dosing range 0–20%
Real-time run data for predictive maintenance planning
Market-leading automatic calibration — visually verifies before calibrating
Fully customized: nozzle count, flow rates, pressure, HMI language, and spray location

Key Benefits

Reduced pre-cure for lower thickness targets. Fully housed pump station to cut dust and cleaning downtime. Improved surface soundness. Rapid return on investment.

Nelspray Engineering

Precision-built in New Zealand.
Installed and supported in India.

Every Nelspray system is custom-engineered for the specific panel board line it serves — then commissioned and calibrated by Clarvigo's local team.

Talk to an Engineer

Belt Spray System

"Flawless spraying, every time." Nelspray's second-generation spray booth — engineered for minimal waste and easy operation.

Automatic Width Control

Follows production width automatically with fine offset adjustment — no manual intervention required.

Two-Chamber Design

Minimizes turbulence around the nozzle for superior spray quality. Fully enclosed chamber cools NelJets® and contains steam.

Multi-Flow-Meter Design

Up to 13-flow-meter configurations for highly accurate spray monitoring. Netzsch progressive cavity pump via IFM flow meters. Dosing range 5–70%.

NelJet® Spray Applicator

"The next generation of high-frequency spray application."

Built to redefine spray control for OSB, MDF, and particleboard lines. NelJet® is the engine behind every Nelspray system.

Fully moulded coil with high-temperature-resistant seals — eliminates internal leakage
PWM (pulse-width modulation) control — standardized, low-waste spray application
Flow capability up to 1.3 L/min @ 3 bar — unmatched performance
ParameterValue
Voltage24V DC, PWM, 0.35A

Flow range0–1300 ml/min @ 3 bar
Liquid supply port1/8" BSP
Electrical connectionMB-3 pin

Alternating Pulse Control (APT)

"The elimination of striping distance."

Traditional PWM spray systems fire all guns together — which can cause striping. APT uses separately timed triggers to fire odd and even guns out of sequence.

The result: a uniform, consistent spray film. Ideal for modern, high-speed production lines.

APT vs Traditional PWM
Traditional PWM: All guns fire simultaneously → striping risk on fast lines
APT: Odd & even guns fire in sequence → uniform coverage, zero striping

Release Agents

Proven chemistry that improves panel quality, press speed, and cost efficiency — formulated specifically for panel board applications.

800 Series

For UF/MUF Resin Systems

Designed primarily for mat spraying in front of the press. Proven chemistry with application rates of no more than 5% without compromising quality.

Improves:

Fiber consolidation — reducing coating costs
Strength test results (IB, MOR, MOE)
Paintability — added customer value
Cure rates — increasing press speed by up to 15%
Product: Release 881 — Data sheet available on request.
900 Series

For pMDI Resin Systems

Concentrated, neutral-based release agent purpose-built for lines running 100% MDI resin. Successfully used on OSB and MDF lines.

Benefits:

Enables production of pMDI-based panels — a more sustainable resin option
Highly water-soluble — can be diluted for press-belt spraying to optimize coverage
Reduces long-term chemical consumption and cost
Product: Release 984 — Data sheet available on request.
