largerSimple-to-operate variable ratio dispensing system
Engineered for specialty materials that require a range or difference in volumetric ratio, the Reactor H-VR allows you to spray ratios from 1:1 to 2.5:1. The system provides infinitely adjustable volume ratio – the operator can dial in the exact volume ratio to adjust the A and B pumps to dispense the correct amount of material.
- For applications that require a range or difference in volumetric ratio
- Allows you to spray ratios from 1:1 to 2.5:1
- Infinitely adjustable volume ratio
- Easy to dial in and adjust the exact output of both A and B materials
- Dispenses polyurethane foams and polyurea coatings
- Built-in steel pallet for easy transport - includes casters
- Single and triple phase configurations including 230 and 400 volts available
- Free applicator training included in CPI’s Foam School

The H-VR, providing consistent, uniform mix of unique materials.
The Reactor H-VR provides infinitely adjustable volume ratio since both A and B pumps can be adjusted to dispense the correct amount of material. The ratio adjustment wheel allows you to dial in the exact volume ratio. As you adjust the volumetric ratio, the stroke length on the fluid pump is shortened or lengthened to reduce or increase the volume of material output. Once you have dialed in the correct volume ratio, simply secure the locking arm to prevent ratio fluctuations.
