What American Geothermal does
American Geothermal is a U.S.-based specialty manufacturer founded in 1981 and headquartered in Murfreesboro, Tennessee, that designs and builds custom batchwater heating and cooling equipment for the concrete industry. The company produces chillers (Chillbatch modular series, 20-120 ton), all-in-one heat pumps (Thermabatch, 20-60 ton, hot water up to 140°F and chilled water at 32.5°F), batchwater tank heaters (Hotbatch, up to 180°F, 5,000-20,000 gallon), cost-effective E-Line systems for smaller plants (under 300 yards/day), gas-fired heaters, and insulated storage tanks. Its core technical differentiator is a proprietary No-Clog Heat Exchanger that allows operation with well, quarry, or city water without filtration or additives, enabling equipment lifespans measured in decades; original 1982 air-source heat pumps remain in service at Argos USA. The company also produces custom digital controls (Advanced Diagnostic PLC) tailored to concrete plant environments and offers mobile trailer-mounted configurations.
Revenue is generated primarily through custom-manufactured equipment sales on a quote-based pricing model with no publicly disclosed pricing, plus an aftermarket service and parts stream offering 24/7 phone support with certified technicians. The go-to-market is sales-led and direct: phone-based enterprise sales, website quote requests, onsite plant evaluations, and active presence at industry trade shows (World of Concrete, The Precast Show, CONEXPO-CON/AGG), with association memberships at NRMCA, NPCA, ACPA, and state concrete associations. The primary customer segment is ready-mix concrete producers needing temperature control to meet ACI guidelines for hot/cold weather and mass concrete placement, with secondary segments in precast manufacturing and industrial process temperature control (the latter handled by sister company Chillmaster). Named enterprise customers include Sierra Ready Mix, Argos USA, and Service Rock. American Geothermal was acquired in 2025 by Swedish investment company Investment AB Latour through its subsidiary Swegon Group, adding the company to a broader portfolio of sustainable climate and process cooling/heating solutions.

Products and services
- AMC Modular Series Chillers (Chillbatch) Modular, expandable batchwater chiller system designed for concrete plants, producing colder water (32.5°F) than any other chiller brand. Features exclusive No-Clog Heat Exchangers, built-in dilution control, dual circuit operation, and Advanced Diagnostic PLC for simplified troubleshooting. Each module contains a Compressor, Condenser, Expansion Valve, and Evaporative Heat Exchanger, and modules operate independently or simultaneously for redundancy, flexibility, and control over cooling capacity (20-120 ton range).
- AMP Modular Heat Pumps (Thermabatch) All-in-one batchwater heating and cooling system for concrete production, producing hot water up to 140°F and cold water at 32.5°F. Available in air-source and water-source configurations, the system is entirely electric with no gas or fuel required, and features the exclusive No-Clog Heat Exchanger for operation with harsh water conditions (20-60 ton range).
- Hotbatch Batchwater Tank Heaters Batchwater tank heater for cold-weather concrete production, producing tempered batchwater up to 180°F. The unit also functions as a chilled batchwater storage tank during summer months. Available in sizes from 5,000G to 20,000G with multiple burner options including Natural Gas, Liquid Propane, and Diesel.

American Geothermal competitors and assessment
Company assessmentRegional players
- Aquatherm (Heat Exchange Engineering): Custom heat exchanger and industrial process cooling equipment manufacturer with similar focus on specialized thermal equipment for process industries. Comparable product overlap in heat exchangers and process chillers; serves adjacent industrial verticals rather than concrete specifically.
Direct peers
- Thermal Care: Manufacturer of process cooling equipment including chillers and temperature controllers for plastics, food, and industrial process applications. Comparable in custom-engineered industrial temperature control equipment with similar small-to-mid-market customer profile.
- EVAPCO: Manufacturer of heat transfer equipment including chillers, cooling towers, and adiabatic/evaporative systems for industrial and process applications. Comparable product overlap in industrial process cooling and heat exchanger technology that American Geothermal relies on for its No-Clog heat exchangers.
- Coldcrete Inc. Specializes in concrete cooling and ice-based batchwater temperature control systems for ready-mix and precast producers. Directly competes with American Geothermal's Chillbatch line in the same niche use case, though takes a different technology approach (ice-based vs. chiller-based).
- ICS Cool Energy: Specializes in temporary and permanent process cooling and heating solutions for industrial customers across food, beverage, plastics, and process manufacturing. Comparable business model of custom-engineered temperature control equipment for industrial end users, though broader in vertical focus than American Geothermal.
Broad incumbents
- Daikin Applied: North American arm of Daikin that manufactures commercial chillers, heat pumps, and process cooling equipment for industrial and HVAC applications. Comparable in chiller and heat pump manufacturing technology; competes for industrial process cooling customers that overlap with American Geothermal's end users.
- Johnson Controls (York): York-brand commercial chiller manufacturer offering industrial refrigeration and process cooling equipment. Comparable product portfolio (chillers and heat exchangers for industrial customers) but serves a much wider range of process and building applications than American Geothermal's concrete focus.
- Baltimore Aircoil Company: Global manufacturer of heat transfer and thermal management equipment including chillers, adiabatic coolers, and heat exchangers for industrial and commercial applications. Comparable in heat exchange technology stack and industrial cooling product lines.
- Carrier Global: Major HVAC and refrigeration equipment manufacturer named by American Geothermal as a source of chillers that competitors modify for concrete use. Comparable in chiller/heating equipment manufacturing but serves a far broader range of building and process applications.
- Trane Technologies: Global HVAC manufacturer whose commercial chillers are explicitly cited by American Geothermal as the products competitors resell into concrete applications. Directly comparable on chiller manufacturing but operates across all commercial/industrial HVAC end markets rather than specializing in concrete.
