We’ve spent years engineering wine cellar cooling units that meet the demands of every kind of project — from small residential cabinets to large commercial cellars. Every series we build gives you the flexibility to accommodate unique spaces, temperature requirements, and installation constraints.
Our 15 product lines cover every installation type: rack-mounted, ceiling-mounted, wall-mounted, cabinet-top, ducted, and high-static systems.
Whether you’re building a custom wine closet or a walk-in commercial cellar, there’s a US Cellar Systems unit designed for the job.
All of our series feature evaporator coils and are built as split refrigeration systems — both ducted and ductless options available.
We are a trade-only wholesale supplier and do not compete with our dealers.
15 Product Lines. One Flexible System for Any Project.
All US Cellar Systems cooling units include evaporator coils and operate as split refrigeration systems — ducted or ductless. Call (562) 513-3017 to speak with our technical team and identify the right unit for your project.
RACK-MOUNTED SYSTEMS
RM Series — Wine Rack Cooler Series
Our most popular and versatile series. RM evaporators mount horizontally, often hidden within the wine racking, with multiple access panels to redirect supply and return vents. Perfect for installation between ceiling joists, in a soffit, or on a wall. Available in single, twin, or triple evaporator configurations.
Capacity: 2,600 – 6,600 BTU/hr | Refrigerant: R134a | ETL Certified
VRM Series — Vertical Rack Cooler Series
The vertical counterpart to the RM Series. VRM evaporators mount vertically with multiple panels to direct or redirect supply and return vents. Can be placed between ceiling joists, in a soffit, or directly on a wall. Available in triple evaporator configurations for larger applications.
Capacity: 2,600 – 6,600 BTU/hr | Refrigerant: R134a | ETL Certified
BR Series — B-Type Replacement Cooling System Evaporator
Designed as a drop-in replacement for existing evaporators of similar configuration. BR units are typically shelf- or wall-mounted within the racking design. They operate on system pressure, eliminating the need for additional control wiring to the condensing unit, making installation straightforward. Title 24 compliant.
Capacity: 2,600 – 5,200 BTUH | Refrigerant: R134a
RMD-EC Series — Rack Mounted Ducted Cooling Systems
Internally insulated ducted evaporators that mount outside the wine room and connect via supply and return air ducts. Extremely low profile that fits in spaces where no other ducted evaporator can. Can be installed in sequence to scale capacity for larger projects. Reversible internal assembly available.
Capacity: 1,800 – 7,200 BTUH | Refrigerants: R134a, R404, R410A, R22 | ETL Certified
HIGH STATIC & DUCTED SYSTEMS
HS Series — High Static Wine Cellar Cooling Series
Powerful ducted evaporators for medium-to-high temperature spaces. The HS Series can be installed up to 25 feet from the wine room, ducting chilled air back in, completely eliminating in-room noise and freeing up valuable storage space. Available with water-cooled condensing units and stainless steel cabinets for coastal or high-corrosion environments.
Capacity: 1,800 – 20,000 BTU/hr | Refrigerant: R134a | ETL Certified

VHS Series — Vertical High Static Systems
The vertical configuration of the High Static series. Delivers the same powerful remote ducting capability as the HS Series — up to 25 feet from the cellar — in a vertical orientation. No in-room noise, no in-room evaporator footprint. Ideal for projects where a vertical unit fits the available installation space better.
Capacity: 1,800 – 20,000 BTU/hr | Refrigerant: R134a | ETL Certified
CEILING-MOUNTED & QUIET SYSTEMS
LPQ Series — Low Profile Quiet Wine Cellar/Humidor Cooling Units
Ceiling-mounted units that deliver exceptionally quiet, dependable refrigeration. An excellent choice for long-term storage, vaulted rooms, and humidors. The LPQ supplies chilled air behind the coil and down the wall, with return air entering through the angled front — promoting natural circulation. Very low maintenance. Twin evaporator configurations available for larger spaces.
Capacity: 1,800 – 8,600 BTU/hr | Refrigerant: R134a | ETL Certified

Q Series — Quiet Low Velocity Systems
Provides low-velocity air flow in two directions — ideal for medium to large wine cellars and sensitive long-term storage environments. Variable speed fan controls allow fine adjustment for noise and humidity stability. Features ultra-efficient ECM motors and an epoxy-coated coil to resist corrosion. NSF Approved.
Capacity: 6,600 – 40,000 BTU/hr | Multiple refrigerants | ETL Certified | NSF Approved
SLA Series — Slim Line Air
Low-velocity, noise-sensitive cooling in a slim, compact profile. The SLA Series uses ultra-efficient ECM motors with variable speed controls, a hinged drain pan for easy maintenance, and a pre-wired electrical panel with screw-type terminal blocks for simple installation. Compatible with glycol or chilled water applications by custom circuiting.
Capacity: 6,600 – 40,000 BTU/hr | Multiple direct expansion refrigerants | ETL Certified
SLPA Series — Super Low-Profile Air
Powerful and efficient in an ultra-low-profile housing that maximizes capacity and airflow for medium to large spaces. The SLPA is purpose-built for sensitive environments where humidity and temperature must remain stable and controlled — quiet, reliable, and easy to maintain. Reverse airflow option available for special applications.
Capacity: 6,600 – 22,000 BTU/hr | Multiple direct expansion refrigerants | ETL Certified
WALL-MOUNTED SYSTEMS
WM Series — Wall Cooler Series
A genuinely unique design that mounts vertically between standard wall studs, similar to a through-the-wall unit, but with no exhaust requirement and only a 1″ projection into the room. Pre-programmed digital thermostat and temperature sensor are factory-installed. Ideal for oddly shaped rooms, under-stair cellars, and spaces with available wall area that can’t accommodate a ceiling or rack mount.
Capacity: 1,800 – 4,600 BTU/hr | Refrigerant: R134a | ETL Certified
DISPLAY & CABINET SYSTEMS
DQ Series — Dual Air Wine Cellar Cooling Quiet Series
Engineered for large wine cabinets and walk-in cellars. DQ evaporators supply two-way air discharge up to 10–12 feet in both directions at medium velocity, with exceptional circulation for long, narrow display cases. Air returns at the bottom, maintaining consistent temperature throughout. Air-defrost coil requires no additional heater.
Capacity: 1,800 – 4,600 BTU/hr | Refrigerant: R134a | ETL Certified
CE Series — Cabinet Evaporator
A slimline, efficient evaporator designed for large wine displays and medium-sized storage rooms. CE units deliver stable humidity and low noise, with ultra-efficient ECM motors that meet or exceed California Energy Commission standards. Compact size preserves maximum storage space. Custom circuiting available for glycol or chilled water applications.
Capacity: 2,600 – 12,000 BTU/hr | Refrigerants: R134a, R404A | ETL Certified
CTE Series — Cabinet Top External Unit Systems
Small evaporators designed for medium-to-large humidity-controlled spaces including wine cabinets, wine walls, fur cabinets, and tobacco humidors. Installs externally to maximize interior storage capacity. This ductless system operates with very low noise and consistent humidity maintained by a steady coil temperature. Anti-corrosion coated coil standard.
Capacity: 2,513 – 3,547 BTU/hr | Refrigerants: R22, R134a, R404a (chilled water by order)
CTI Series — Cabinet Top Internal Evaporators
A compact internal evaporator with a 6″ profile, designed for medium-to-large humidity-controlled spaces such as wine cabinets, wine walls, and humidors. This ductless system can be installed horizontally near the cabinet top, maximizing installation flexibility while minimizing the cooling unit footprint inside the cabinet.
Capacity: 1,537 – 3,546 BTU/hr | Refrigerants: R22, R134a, R404a (chilled water by order)
WCC Series (CC Series) — Wine Cabinet & Closet Cooling Units
Previously designed for wine closets and cabinets, these evaporators distributed refrigerated air quietly up to 10 feet in both directions, returning air to the front. Best-in-class cooling per cubic inch of installation space made them ideal for high-traffic areas and low set-point applications such as white wine storage.
