Greenhouse Gearbox
Product Range

The decision is driven primarily by vent length and synchronisation requirements. For individual vents under 8 metres, a GG-VT gearbox at the vent end provides a cost-effective solution with full self-locking capability. For continuous ridge vents exceeding 20 metres — typical of multi-span Venlo glasshouses — GG-RP rack and pinion systems are mechanically necessary, because they distribute drive force across multiple synchronised points along the vent length.

As a rule of thumb: under 20 m of vent, specify GG-VT; over 30 m, specify GG-RP; between 20 and 30 m, either system can work depending on vent panel weight and wind load.

No. While the core mechanical principle is similar to a standard worm reducer, the GG-SC series is engineered specifically for greenhouse curtain applications with three critical differences: optimised lead angle for sub-55 dB operation at rated load, S3-40 percent duty cycle rating sized for typical curtain cycling patterns, and integration-ready shaft geometry that matches industry-standard curtain wire pulley dimensions.

Using a generic industrial worm reducer in a greenhouse curtain application typically results in noise levels above 65 dB, thermal overload during summer peak cycling, and shaft adapter fabrication requirements that erase the cost advantage of the off-the-shelf unit.

Technically yes, but it is not the most cost-effective choice. The GG-RF series is optimised for high starting torque to break the static friction of polyethylene film against guide tubes — a requirement specific to flexible film greenhouses. For hard-frame glass or polycarbonate greenhouses, the GG-VT series delivers equivalent operational torque at lower cost because the starting torque envelope is significantly smaller.

The exception is retrofit projects where mechanical interfaces from a previous film installation are being reused — in that scenario, GG-RF compatibility may simplify the upgrade.

Yes. Our spare parts range is dimensionally compatible with the most common European brands installed in greenhouses worldwide: Ridder (RW and RS series), Sercom Drive systems, and legacy Arion curtain drives. Before quoting a replacement, we strongly recommend sending a photograph of the existing unit's nameplate so our engineering team can confirm the exact model series, shaft diameter, mounting hole pattern, and any non-standard modifications.

Stocked replacement items typically dispatch within 48 hours of confirmed order — crucial during peak production season when downtime carries crop-loss risk.

Our standard MOQ for OEM custom production runs is 50 units per design. Below this quantity, the tooling amortisation cost makes custom development economically impractical for both parties. For prototypes and pilot runs we can produce as few as 5 units, but at custom tooling rates that reflect the actual setup cost.

For OEM partners with long-term volume commitments above 500 units per year, we provide dedicated production scheduling and inventory consignment arrangements. Reach out via our contact page to discuss specific commercial terms.

Yes. Every gearbox across our product range carries our standard 24-month warranty from date of delivery against defects in materials and workmanship under normal operating conditions. Extended warranty programmes of 36 and 60 months are available for OEM partners and large project purchases above 500 units.

Warranty claims require a brief failure report and photographs. We aim to dispatch replacement units within 5 business days of claim approval — and we maintain a 2,000-unit safety stock specifically to honour that commitment without delay.
