Every greenhouse automation project carries its own load curve, climate profile, and structural constraints. Generic catalogue answers rarely solve real-world specification problems — and the cost of a wrong gearbox choice surfaces months after installation, deep into a production season.
When you reach out to Ever-power, your inquiry goes directly to our mechanical engineering team, not a generic sales queue. We typically respond within one business day with a technical specification, dimensional drawing reference, and price indication based on your actual application data — vent area, wind load, operating voltage, climate zone, and target lead time.
All fields with * are required. The more detail you share, the faster we can respond accurately.
Common reasons buyers, engineers, and project managers reach out — and what information helps us respond most precisely in each case.
Looking for a quotation on standard GG-VT, GG-SC, or GG-RF series gearboxes from our published catalogue? Include the model, quantity, and target delivery date.
For private label, custom dimension, or unique torque requirements, our OEM team responds with a feasibility note and prototype timeline within 48 hours.
Need a direct replacement for an existing European brand gearbox? Photograph the nameplate of the old unit — we will confirm dimensional compatibility before quoting.
Our team operates on rolling shifts to cover Asia, Europe, and Americas business hours. Below are our headquarters details and standard service windows.

Our sales and engineering team speaks multiple languages to ensure clear technical communication across global projects.
When you submit an inquiry through our form or send us an email, here is exactly what happens — step by step, with the timing you can expect.
Your message is routed automatically to the right engineer based on inquiry category.
Engineer reviews load profile, application, and verifies preliminary feasibility.
You receive recommended model, indicative price, lead time, and any clarifying questions.
After alignment on specs, formal quotation with DDP/FOB terms and payment options.
Quick answers to the questions buyers and project managers ask before sending a formal inquiry. Browse our full greenhouse gearbox product line for in-depth technical details.
For a useful first response, please share: the gearbox category (ventilation, curtain drive, rolling film, rack and pinion), the application (vent area in m2 or curtain span), the required operating voltage, the target IP rating, the expected operating temperature range, and the quantity. Approximate values are perfectly acceptable for initial inquiries — we will refine specifications through a follow-up exchange.
For OEM projects, a sketch or CAD drawing of the mounting interface saves us several iterations and accelerates feasibility confirmation. Photographs of an existing installation are equally helpful for compatibility checks.
Standard inquiries submitted during Chinese business hours (UTC+8, 08:30 – 18:00 Mon–Fri) receive a first technical response within four business hours. Inquiries submitted overnight from Europe or the Americas typically receive a reply within 12–18 hours of submission. The maximum response window for any inquiry — including weekend submissions — is 24 hours.
Urgent project deadlines? Mention this clearly in the message subject line and we will prioritise dispatch.
Yes. For most standard catalogue gearbox models we can dispatch evaluation samples within 5 business days. Sample units carry the standard catalogue price; freight is at the customer's expense unless waived as part of a confirmed bulk order intent. For OEM custom samples, the timeline is 15 working days from drawing approval, with sample tooling cost typically credited against the first production order.
Absolutely. We can sign either our standard mutual NDA template (available in English and Chinese) or your own NDA, prior to any technical discussion. Reference our standard OEM workflow on the company profile page for additional details on confidentiality practices.
For first-time customers, we typically work with 30% T/T deposit on order confirmation and 70% balance against B/L copy. Repeat customers and verified OEM partners are eligible for L/C at sight or extended terms. We invoice in USD, EUR, or RMB; bank transfer, irrevocable L/C, and PayPal (for sample orders only) are all accepted.
For shipments above USD 50,000, we can offer custom payment schedules tied to production milestones.
Yes. For project orders exceeding 100 units or strategic OEM partnerships, we offer two training formats: remote video training (1.5-hour live session via Zoom with our chief engineer) at no charge, and on-site training at the customer's facility (engineer dispatch, customer covers travel and accommodation). Training covers installation best practices, common failure modes, preventive maintenance schedules, and basic troubleshooting.
For urgent project deadlines or open-ended exploratory discussions, email us directly or schedule a 30-minute technical consultation with our chief engineer. No commitment, no pressure — just honest answers to real engineering questions.
