FAQs

Do you offer OEM or ODM customization for Fan Coil Units?

Yes. We are a direct manufacturer. Our engineering team supports full “0-to-1” bespoke designs, including custom voltages (115V/230V), specific IP ratings, and unique dimensions tailored to your local market requirements.

What is your Minimum Order Quantity (MOQ)?

For standard stock models, our MOQ is highly flexible to support your trial orders. For specific OEM designs or custom EC motor configurations, MOQ varies based on production requirements. Please contact our sales team to discuss details.

What is the standard lead time for bulk orders?

Our standard lead time is typically 15 to 25 days after deposit confirmation. For highly customized OEM projects or peak season volume runs, it may extend to 30-45 days. We provide transparent production schedules to protect your supply chain.

Are your HVAC products certified for strict import markets?

Absolutely. Our Fan Coil Units and motors carry CE, RoHS, and BSCI certifications, and are manufactured under strict ISO standards. This ensures total compliance with international safety regulations for smooth customs clearance.

Why should we choose EC motors over standard AC motors?

EC (Electronically Commutated) motors consume about 30% less energy than standard AC motors. They offer precise 0-10VDC speed control, generate less heat, operate much quieter, and significantly lower the total cost of ownership for end-users.

What is the warranty period for LONGWELL units?

We provide a solid 1-year standard warranty on our Fan Coil Units and motors. If any verifiable manufacturing defect occurs within this period, we will supply free replacement parts or new units according to our contract terms.

Can we equip the units with Carbon or HEPA filters?

Yes. While standard configurations use washable nylon or G3/G4 synthetic filters, we frequently customize units with high-grade Carbon filters for odor control or HEPA filters for cleanroom applications based on your exact project needs.

What ambient temperatures can these fan coil units handle?

Built with premium galvanized steel and maintenance-free ball bearings, our robust units are engineered for extreme environments. Most of our models run safely and continuously in ambient temperatures ranging from -25°C up to 60°C.
