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-0100-4 is a fit for compressed air systems that need an RHT Series high inlet temperature refrigerated air dryer with 100 SCFM inlet flow rating at 100 PSIG, 1-1/2" NPT connections, and an electrical configuration of 460 VAC, 3 Phase, 60Hz.
Frequently Asked Questions
Altec AIR RHT-0100-4 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.
