12V Truck Parking AC Manufacturer for US Wholesale & OEM
Originally published May 19, 2026 · Updated October 18, 2026

Vethy (Qingdao Vethy Industrial Co., Ltd.) supplies 12V and 24V parking air conditioners for distributors, importers, upfitters and OEM purchasing teams. For US 12V truck projects, begin with a model-specific specification and a sample validation plan. Parking AC, parking cooler, battery-powered truck AC and engine-off cab cooling describe related purchasing needs; the installation and power requirements still depend on the selected model.
US 12V models to evaluate
These are separate configurations. Use the linked model pages for their current ratings and dimensions, then confirm the order specification in writing.
- VX3000SP 12V split parking AC: a cooling-focused starting point for sleeper-cab projects. Its published 12V cooling rating is 7,000 BTU/h; do not substitute the separate 24V rating.
- EcoMax 3S 12V split parking AC: a configuration with published cooling and heating ratings. Confirm the intended ambient range and heating performance for the actual application.
- 12V rooftop parking AC range: review a rooftop layout when the cab roof, mounting arrangement and service access suit the project.
Model references above come from Vethy's current product pages, reviewed October 18, 2026. Published ratings are supplier specifications, not independent vehicle-test results. A 12V supply rating alone does not establish compatibility with every US truck.
From wholesale inquiry to an approved OEM configuration
- Define the project. Send your company role, vehicle make/model/year, sleeper layout, 12V power source, intended operating conditions, pilot quantity and expected annual volume.
- Define the configuration. Agree on the model revision, indoor and outdoor mounting, included parts, wiring and drainage requirements. For private label or OEM work, specify the branding, packaging, manual language, harness or mounting changes you want reviewed.
- Agree on the sample plan. Request sample availability, cost and lead time. Record cooling performance, energy use, noise measurement conditions, fit and service access in a representative vehicle.
- Approve the production specification. Confirm the bill of materials, drawings, labeling, acceptance criteria, applicable documentation, warranty and replacement-parts process in writing before a bulk order.
- Plan repeat supply. Request a production schedule, shipment terms, packaging details and change-control process for repeat orders. Private-label and engineering scope depend on the agreed project.
Documents and terms to request with a quotation
- Technical: model-specific data sheet, dimensional and mounting drawings, electrical input data, installation instructions, operating limits, included-parts list and service-parts list.
- Testing: test conditions and reports for any runtime, sound-level or performance claim you plan to use in your market. Battery capacity, usable energy, ambient temperature and other loads must accompany a runtime comparison.
- Market documentation: request the actual reports or certificates relevant to the selected model and intended US application. Check the named manufacturer, model scope, issuing body and validity; a generic certificate list does not establish a specific product's status.
- Commercial: current MOQ, quantity breaks, sample charges, customization charges, production lead time, payment terms, delivery terms and destination. These must be confirmed for the quoted configuration.
- After-sales: written warranty duration and exclusions, claim evidence, replacement procedure, spare-parts availability and responsibility for installation or service labor.
Buyer questions
What is the minimum order quantity for wholesale or private label?
Request the current MOQ for your exact model, pilot quantity and customization scope. Stock configurations, packaging changes and engineering changes can require different quotations.
Can a parking AC replace every function of a diesel APU?
Compare the functions your project needs. Cab cooling, heating, battery charging and auxiliary power are separate requirements. Specify which functions the selected equipment and vehicle installation will provide.
Can we advertise a fixed overnight runtime?
Use measured results for a defined installation. Record usable battery energy, ambient conditions, cabin target, cooling load and other electrical loads. Avoid a universal runtime promise based only on the AC model name.
