FAQ

Q1: Can HVAC retrofit projects be completed without stopping factory production?

In many retrofit projects, ductless systems allow phased installation, which reduces disruption to daily operations. Installation can often be scheduled in stages or during low production periods to minimize downtime.

Q2: Is ductless retrofit suitable for steel structure factories?

Yes. Steel structure factories often have limited space for duct installation. Ductless industrial air conditioners can be mounted directly on walls or suspended from structures, making them suitable for this type of building.

Q3: Does retrofit improve energy efficiency?

In many retrofit scenarios, upgrading to ductless systems improves airflow distribution and reduces energy loss associated with duct leakage. Improved zoning and control methods can also contribute to better overall energy performance.
