Six free calculators for walk-in cooler and freezer decision-making, sized to ASHRAE Refrigeration Handbook Ch. 24, IEC 60335-2-89:2019, and NIST REFPROP. Built in Hudson, NY — grounded in U.S. metro ambient conditions, Foster panel U-values, and the EPA AIM Act refrigerant transition.
Size the refrigeration capacity for your walk-in — by application, geometry, panels, product, and U.S. metro ambient.
→ Tool · 02Compare two panel-thickness scenarios. Annual USD cost, savings, payback period, 10-year NPV.
→ Tool · 03 · EPA AIM ActVerify minimum floor area for A2L refrigerants per IEC 60335-2-89:2019 — the calculation behind the 2026 low-GWP refrigerant transition.
→ Tool · 04Estimate total system charge from line lengths, climate, and equipment. 12 refrigerants — R-449A, R-454C, R-290, R-717.
→ Tool · 05Air-cooled condenser capacity from evaporator load, ambient, and refrigerant. Hot-climate ambient derate built in.
→ Tool · 06What is spoilage costing you right now? What does a walk-in cost? When does it pay back? Four inputs, three numbers, a 10-year cash chart.
→ Build & Quote · Live 3DSized your load, checked your refrigerant — now configure the real thing. Live 3D, ASHRAE heat-load math, PDF spec sheet, price in 60 seconds.
→Computed a load, sized a room, picked a refrigerant — now let our engineers verify and quote.
