Chillers
Share the design duty, water temperatures, power supply and any existing system requirements.
COMMERCIAL HVAC PROCUREMENT
Equipment for your building project.
Work with Tongxing to review your equipment requirements, technical documents and delivery needs. For contractors, importers and project purchasing teams coordinating supply with local engineers.
Discuss your projectStart with the equipment scope.
Send an equipment schedule or describe the building use and required duty. We can discuss individual systems, multiple-unit purchases and equipment packages for new projects or replacements.
Rooftop packaged units
Coordinate capacity, supply airflow, external static pressure and site connections.
VRF systems
Review indoor and outdoor equipment together with room layouts, controls and piping requirements.
Precision air conditioning
Discuss the facility, equipment duty, cooling arrangement and required technical documents.
For a water-cooled system, explore the water-cooled chiller range and share your site and system requirements.
PRECISION AIR CONDITIONING
Define the facility and cooling task.
Tongxing supplies precision air conditioning equipment. Tell us the facility type, required cooling duty, operating conditions and whether the project uses a direct-expansion or chilled-water arrangement. Include available electrical supply, controls, monitoring and standby requirements.
We will discuss the applicable series, configuration and available technical documents for your project. For a data centre, identify the equipment you are sourcing and the interfaces handled by your local engineering team.
Discuss precision air conditioningPROJECT RESPONSIBILITIES
Coordinate supply with your local team.
Equipment and selection
Share the project requirements and equipment schedule. We discuss suitable options, available technical documents and the agreed scope of supply.
Local installation and service
Your local team carries out installation, commissioning and after-sales service. Confirm site responsibilities and required equipment information before ordering.
Remote and on-site support
Tongxing can provide remote technical support. Where a site visit is needed, its scope, timing and costs are agreed for the individual project.
From project brief to equipment proposal.
Share the project
Give the installation country, building use, your purchasing role and target schedule. If known, include the equipment budget separately from the building and installation budget.
Confirm selection inputs
Review loads, operating conditions, electrical supply and site interfaces with your engineering team. Identify which drawings, schedules and required market documents are available.
Compare the proposal
Check the exact model list, quantities, configuration and included accessories. Agree the delivery requirements, support scope and outstanding technical questions before placing an order.
