Installation & Application Notes
- Verify operating limits: Confirm inlet temperature and system pressure stay within listed limits (Up to 200°F; 232 PSIG).
- Use published sizing basis: The inlet flow ratings are shown as “SCFM @ 100 PSIG” with sizing based on: Inlet Temperature 180°F; Inlet Dew Point of 160°F; Inlet Pressure of 175 PSIG; Outlet Dew Point of 50°F.
- Corrected capacity method (variable conditions): Corrected Inlet Flow Capacity = INLET Flow (above) × Inlet Pressure Correction Factor (A) × Inlet Temp Correction Factor (B) × Ambient Temp Correction Factor (C).
- Correction factor tables: A: 100 PSIG (0.80), 125 PSIG (0.88), 150 PSIG (0.95), 175 PSIG (1.00), 200 PSIG (1.04). B: 100°F (3.31), 125°F (1.99), 150°F (1.30), 180°F (1.00), 200°F (0.91). C: 80°F (1.08), 90°F (1.06), 100°F (1.00), 110°F (0.90), 120°F (0.76).
The Altec AIR RHT-0120-4 is a fit for compressed air systems that need an RHT Series high inlet temperature refrigerated air dryer with 120 SCFM inlet flow rating at 100 PSIG, 2" NPT connections, and an electrical configuration of 460 VAC, 3 Phase, 60Hz.
Frequently Asked Questions
Altec AIR RHT-0120-4 High Inlet Temperature Refrigerated Air Dryer
▶️ Question: What compressor type is the RHT Series designed to be used with?
Answer: The price guide states the RHT Series is designed to be used with tank mounted piston-type air compressors that have no after-coolers.
▶️ Question: What is the listed high inlet temperature capability?
Answer: The RHT Series lists high inlet temperature capability up to 200°F.
▶️ Question: Does the RHT Series require separate after coolers, separators, or drains?
Answer: The price guide lists that the RHT Series does not require separate after coolers, separators, or drains.
▶️ Question: How do I size an RHT dryer when inlet conditions vary?
Answer: The price guide provides a corrected inlet flow capacity method: Corrected Inlet Flow Capacity = INLET Flow (SCFM @ 100 PSIG) × Correction Factor (A) × Correction Factor (B) × Correction Factor (C). It also provides correction factor tables for inlet pressure (A), inlet temperature (B), and ambient temperature (C).
▶️ Question: What does the “P” option indicate?
Answer: The model table defines “P” as a programmable timer installed. For RHT-0010-1, RHT-0015-1, and RHT-0020-1, the programmable timer is listed as not available. For other listed models, “-P” indicates the programmable timer installed configuration.
