Ref Tools offers a collection of useful air conditioning and refrigeration tools: Refrigerant Slider As a featured part of Ref Tools, you get all the features and functionality that made Refrigerant Slider a hit with millions of installers around the world. Quickly calculate pressure/temperature ratios and find essential information on over 80 refrigerants. Magnetic Tool Test and troubleshoot solenoid valve coils quickly and easily. Troubleshooter Get help diagnosing issues in refrigeration systems, so you can quickly identify symptoms and find recommended solutions. Product Finder Find extensive product-related data in one place. Search by product code number or product category to access and share product specifications, documentation, visuals, and more. Spare Parts Access and order an extensive list of Danfoss spare parts and service kits for air conditioning and refrigeration applications. Low-GWP Tool Find and compare climate-friendly refrigerants for retrofitting by checking compatibility with the TXV. TXV Superheat Tuner Optimize superheat in less than 15 minutes. Using advanced algorithms, TXV Superheat Tuner provides valve-specific adjustment recommendations. Podcasts The workday can be full and the road long, so Ref Tools also provides you with some educational entertainment. You can listen to podcasts, including the popular Chilling with Jens podcast, directly in the app. So, take a break and chill out a bit while learning something new about refrigeration. More about Refrigerant Slider Refrigerant Slider, now a part of Ref Tools, helps you quickly calculate the pressure-to-temperature ratio for more than 80 refrigerants, including natural refrigerants such as ammonia and transcritical CO2. Refrigerant Slider also provides you with information about each refrigerant, including Global Warming Potential (GWP) and Ozone Depleting Potential (ODP). You can switch between the IPCC AR4 and AR5 values, where AR4 values are used in relation to the European F-Gas regulations. Refrigerant Slider’s P/T calculations use extended curve–fitting models based on Refprop 10 results. You can also see both dew and bubble point for refrigerants with glide. Streamline your workflow Ref Tools goes beyond just providing quick access to helpful tools; it helps you save time by allowing you to track your most visited service sites and save unique settings for each one. Simplify each service call with ease. Feedback Your input matters – we would love to hear it from you. We're committed to continuously improving Ref Tools to meet your needs. If you encounter a bug or have a feature suggestion, please use the in-app feedback function available in Settings. Alternatively, you can reach us via email at coolapp@danfoss.com.

Gauge is a field toolkit for HVAC and refrigeration technicians: a pressure-temperature chart for 10 refrigerants, superheat and subcooling calculators, troubleshooting checklists and a service call log with PDF reports. PT CHART - R-410A and R-22 free; R-134a, R-407C, R-404A, R-32, R-454B, R-290, R-438A and R-422D with Pro - Look up the saturation temperature for a pressure, or the pressure for a temperature - Scroll the full table from -40°F, with safety notes for the A2L (R-32, R-454B) and A3 (R-290) refrigerants CALCULATORS - Superheat: suction pressure and suction line temperature give the saturation temperature and the superheat - Subcooling: liquid line pressure and liquid line temperature - Temperature split: return and supply air - Ohm's Law: enter any two of volts, amps, ohms and watts - Pro: airflow (required CFM from BTU/h or tons and the temperature split), duct sizing (round and rectangular sizes from CFM and air velocity), capacitor check (measured against rated µF) and voltage drop (copper wire by AWG, one-way length, amps and supply voltage) Superheat, subcooling, temperature split, capacitor and voltage drop results are color-coded against typical ranges, with what to check next. SERVICE CALL LOG - Customer or address, complaint, system type, make and model - Suction and liquid pressure, superheat, subcooling, suction line, liquid line, supply and return air temperatures, compressor amps - Your diagnosis, the work performed, refrigerant type and amount, parts, notes, cost and time on the job - Free: up to 10 service calls. Pro: unlimited calls, search, and a PDF service report with your name and certification that you can share with the customer REFERENCE - Step-by-step checklists: AC not cooling (free), furnace not heating and heat pump not heating (Pro) - Typical ranges for superheat, subcooling, temperature split and compressor amps - Refrigerant facts: GWP, A2L or A3 safety class and phase-down status - System types, a copper wire ampacity table and an EPA 608 overview (certification types and key rules) AI ADVISOR (PRO) Describe a symptom or a set of readings and get a short written answer from an AI model. It sends only the message you type and needs an internet connection. AI answers can be wrong: check them against your own readings and the equipment manufacturer's data. GOOD TO KNOW - Gauge works in US units: °F, psig, CFM, inches, feet, AWG and pounds - The PT chart, calculators, reference and service log work without a connection GAUGE PRO Free: the PT chart for R-410A and R-22, the superheat, subcooling, temperature split and Ohm's Law calculators, up to 10 service calls, the AC checklist and the reference tables. Pro adds the other 8 refrigerants, the airflow, duct sizing, capacitor and voltage drop calculators, unlimited service calls with search and PDF reports, the furnace and heat pump checklists and the AI Advisor. In the US, Gauge Pro is $4.99 a month or $39.99 a year (US prices; other countries see their own price in the app). Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Manage them in your App Store account settings.
