1 / 19Thermo King SG-5000 Genset Tier 4 Standards
The Thermo King SG-5000 genset is made in the USA, available in clip-on and undermount formats, built to power all ISO reefers on the market.
Full Description
Manufactured in the United States, the Thermo King SG-5000 clip-on genset is built to keep temperature-sensitive cargo protected regardless of ambient conditions, delays, or route. It carries lifetime CARB compliance and meets full EPA Tier 4 standards for off-highway diesel engines, so the unit stays compliant for its entire service life without the need for later retrofits. Inside, a large-diameter alternator with reinforced bearings and high-specification rotating diodes pairs with an engine-driven coolant fan and premium corrosion protection to keep the unit running in demanding conditions. It's rated to power any ISO reefer on the market and is offered in clip-on (approximately 828 kg) or undermount (approximately 686 kg) configuration, with an engine tuned for faster throttle response and built-in two-speed fuel-saving technology. Service is needed once every 3,000 hours. The genset runs on an advanced Thermo King controller with automated pre-trip testing, self-check diagnostics, alarm monitoring, auto-restart, and event data logging. An optional telematics package tracks position, fuel, engine hours, and running parameters in real time by road, rail, or terminal. Fuel capacity is 473 liters (125 gallons), and forklift pockets are standard. CSC certified, and available in new and used condition.

Common Questions
How does the deposit and reservation process work?
A refundable deposit of up to $1,000 (or the item's full price if it's lower) holds this unit and locks the quoted price for 48–72 hours while we confirm availability and arrange delivery. If your order doesn't move forward, the deposit is fully refunded.
Do you deliver, and does it cost extra?
Yes, we deliver nationwide. Delivery is coordinated after reservation and quoted based on your location and the unit's size, so it isn't included in the listed price.
What's your return policy?
Returns are accepted within 7 days of delivery. Return shipping and any related costs are the customer's responsibility.
Can I write this purchase off as a business expense?
Businesses may qualify to deduct the full purchase price in the year it's placed in service under Section 179, rather than depreciating it over several years. Rules and limits vary, so this isn't tax advice — talk to your accountant about your specific situation.
