A Thermo King SG-3000 undermount (underslung) diesel generator set for reefer containers, mounted beneath the chassis for a low-profile install.
Full Description
The SG-3000 is an underslung diesel generator set (genset) that mounts beneath a truck or container chassis rather than clipping onto the outside, keeping the unit out of the way for operators who need that clearance. It's built by Thermo King for reefer container power applications where reliability and 24/7 service support matter.

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.
