What Is the Summit EQTemp ACR Series?
EQTemp® is Summit’s healthcare-focused refrigeration line. In practical terms, EQTemp models are built for clinical workflows where temperature stability, alarms, access control, and monitoring readiness matter.
The ACR series refers to “all-refrigerator” medical units designed for controlled cold storage (commonly +2°C to +8°C) for vaccines, medications, and specimens. Many ACR models share a consistent set of workflow features: digital microprocessor control with external readout, high/low alarms, self-closing doors with magnetic gaskets, factory-installed locks, and hospital-grade cords (“green dot” plug).
For buyers comparing across categories, Summit EQTemp ACR is often chosen as an affordable vaccine refrigerator for clinic and small-to-mid facility use where you want purpose-built features without jumping to more expensive enterprise brands.
Where it fits in your cold chain stack: Start with the medical refrigeration hub for category-level browsing: Medical Refrigeration. If you’re selecting for vaccines or pharmacy-grade workflows, also browse Vaccine and Pharmacy Refrigerators. For labs, compare with Medical & Lab Refrigerators.
Summit EQTemp ACR Model Comparison: Full Lineup
This is the “model-level” section. If you’re searching Summit ACR1012G review or Summit ACR1012G vs ACR1322G, you’re trying to choose capacity and workflow fit, not read generalities.
Compact Models (1.58–1.94 cu.ft.)
| Model | Capacity | Door | Best For | NSF/ANSI 456 Version | LHD Version |
|---|---|---|---|---|---|
| ACR161W | 1.58 cu.ft. | Solid | Ultra-compact med/vaccine storage in low-traffic rooms; insulation-first choice | ACR161WNSF456 | ACR161WLHD |
| ACR162G | 1.58 cu.ft. | Glass | Compact storage where staff benefits from quick visual checks (less “search time”) | ACR162GNSF456 | ACR162GLHD |
| ACR21W | 1.94 cu.ft. | Solid | More compact capacity when you need additional tray depth for meds or small vaccine programs | ACR21WNSF456 | ACR21WLHD |
| ACR22G | 1.94 cu.ft. | Glass | Busier compact workflows where quick visibility reduces door-open duration | ACR22GNSF456 | ACR22GLHD |
Undercounter / Built-In Models (3.17–3.88 cu.ft.)
| Model | Capacity | Door | Install Type | Best For | NSF/ANSI 456 Version |
|---|---|---|---|---|---|
| ACR31W | 3.17 cu.ft. | Solid | Freestanding | Clinic back room, nurse station, pharmacy overflow (freestanding placement) | ACR31WNSF456 |
| ACR32G | 3.17 cu.ft. | Glass | Freestanding | Visibility-first, faster item finding in tighter rooms | ACR32GNSF456 |
| ACR51W | 3.88 cu.ft. | Solid | Front-breathing built-in OR freestanding | Undercounter placement in exam rooms, pharmacy counters, lab benches | ACR51WNSF456 |
| ACR52G | 3.88 cu.ft. | Glass | Front-breathing built-in OR freestanding | Busy undercounter workflows: visibility + built-in installation flexibility | ACR52GNSF456 |
Comparison note: ACR31W/ACR32G vs ACR51W/ACR52G is primarily an installation question. ACR51/52 are front-breathing and can be built-in under a counter. ACR31/32 are freestanding. If you truly need built-in undercounter placement, shortlist ACR51/52.
Upright Models (9.88–15.53 cu.ft.)
| Model | Capacity | Door | NSF/ANSI 456 Version | LHD Version | Best For |
|---|---|---|---|---|---|
| ACR1012G | 9.88 cu.ft. | Glass | ACR1012GNSF456 | ACR1012GLHD | Mid-size clinic, growing pharmacy; common “first full-size” Summit vaccine refrigerator |
| ACR1322G | 12.71 cu.ft. | Glass | ACR1322GNSF456 | ACR1322GLHD | Large clinic, multi-provider practice; better seasonal buffer and organization |
| ACR1602G | 15.53 cu.ft. | Glass | ACR1602GNSF456 | ACR1602GLHD | High-volume pharmacy, regional health department, institutional programs |
| ACR1321W | 12.71 cu.ft. | Solid | ACR1321WNSF456 | ACR1321WLHD | Solid-door alternative when insulation + light control are preferred |
| ACR1601W | 15.53 cu.ft. | Solid | ACR1601WNSF456 | ACR1601WLHD | Largest solid-door option for programs prioritizing insulation/light control |
Comparison note for ACR1012G vs ACR1322G vs ACR1602G: This is an inventory + growth decision. If your program experiences seasonal peaks (e.g., flu clinics), the “one size larger” choice often prevents overcrowding and chaotic re-stocking.
ADA-Compliant Option (Combo)
| Model | Capacity | Type | Install | Best For |
|---|---|---|---|---|
| CT663BKCSSADA | 5.1 cu.ft. | ADA refrigerator-freezer combo | Built-in undercounter | Facilities requiring ADA height with combined fridge/freezer in limited space |
Program note: Combination units can be useful for space, but vaccine programs often specify purpose-built vaccine storage. If vaccines are involved, confirm program guidance before choosing combo configurations.
NSF/ANSI 456 vs Standard ACR: Do You Need the Certified Version?
NSF/ANSI 456 is a voluntary vaccine storage performance standard. In procurement terms, it reduces ambiguity: if your program requires NSF/ANSI 456, shortlist certified models first and then decide size and door type.
How to spot it: Summit models with the NSF456 suffix include a NIST-calibrated buffered temperature probe and calibration documentation. For many audited workflows, this is the simplest path to standardizing monitoring readiness.

Glass Door vs Solid Door: Choosing Your ACR Door Type
Door choice is a workflow decision. Glass doors can reduce door-open time by helping staff locate items faster. Solid doors can support insulation and light control.
Glass door (G suffix): visibility + faster picks
- Less “search time” during busy workflows
- Can reduce door-open duration when staff routinely checks inventory
- Often preferred for higher-traffic clinics and immunization programs
Solid door (W suffix): insulation + light control
- Often preferred when light-sensitive storage policies exist
- May be favored in lower-traffic rooms prioritizing insulation
- Useful when access is more controlled and door openings are less frequent
Undercounter vs Freestanding vs Upright: Which Form Factor?
Most wrong orders happen when teams choose a model by capacity but ignore installation reality. Use this order: (1) capacity need, (2) placement type, (3) NSF456 requirement.
Compact freestanding
Best for small offices, school nurse rooms, or point-of-care rooms where space is tight and storage volume is limited.
Undercounter built-in (front-breathing)
Best when the refrigerator must integrate into cabinetry (exam rooms, pharmacy counters, lab benches). Front-breathing designs like ACR51/52 support built-in installation.
Upright full-size
Best when inventory and organization matter most—public health programs, larger clinics, and busier pharmacies.

Left-Hand Door (LHD) Options: When Door Swing Matters
Door swing can quietly break a workflow. If the unit is placed near walls or cabinetry, the wrong swing can create awkward access or block traffic. Many Summit ACR models offer LHD versions, choose the swing that matches how staff approaches the unit.
- Upright LHD example: ACR1012GLHD
- Compact LHD example: ACR22GLHD
- Built-in LHD example: ACR52GLHD
