Frequently Asked Questions
QWhat is the standard delivery lead time?
Standard models ship within 45 days from contract signing and down payment. Custom projects 60-75 days. Specifics confirmed in contract.
QHow do I choose between gas and electric heating?
Where natural gas is reliably available at competitive cost, gas heating typically reduces operating costs by 35%-50% compared to electric heating for continuous operation. Electric heating's advantages: zero local emissions, easy maintenance, lower upfront cost. The choice depends on your local energy prices and emission requirements.
QCan I visit MUSI's factory to see this equipment?
Absolutely. International visitors are warmly welcome at our Changzhou factory. We can show in-process equipment and videos of running customer installations. Book at least 1 day in advance — we provide pickup and engineer-led tours.
