FAQ - Hospital Chillers

Question 1

Why do hospitals need special chillers?

Accepted Answer

Hospitals require chillers with high reliability (redundancy), low noise (sensitive environments), thermal precision (medical equipment), and compliance with sanitary standards. Helioterm HTH line hospital chillers meet all these requirements, ensuring continuous 24/7 operation in critical environments.

Question 2

Which chiller to use for magnetic resonance imaging (MRI)?

Accepted Answer

Magnetic resonance imaging equipment requires chillers with high precision (±0.5°C), low vibration, and quiet operation. We recommend HTH 09 to HTH 15 models with redundancy, ensuring that the MRI equipment never runs out of cooling.

Question 3

What is the ideal temperature for a surgical center?

Accepted Answer

Surgical centers must maintain a temperature between 20°C and 24°C, with a relative humidity of 45% to 55%. Our HTH hospital chillers provide chilled water at 7°C for fancoils or AHUs that condition these environments with precision and air renewal according to ANVISA standards.

Question 4

Does the hospital chiller meet ANVISA standards?

Accepted Answer

Yes, our HTH line hospital chillers are designed according to NR10, NR12, ANVISA's RDC 50 and NBR 7256 for healthcare environments. We offer AISI 304 stainless steel reservoir, IP55 protection, and complete documentation for system validation.

Question 5

What happens if the hospital chiller fails?

Accepted Answer

Our HTH 15 to HTH 60 hospital chillers have 100% redundancy with two independent refrigeration circuits. If one circuit fails, the other automatically takes over the load, ensuring continuous operation. The PLC controller has configurable alarms and fault display for monitoring.

Question 6

What is the acceptable noise level for a chiller in a hospital?

Accepted Answer

For hospital environments, the recommended noise level is below 65 dB(A). Our HTH hospital chillers meet this requirement with a special acoustic cabinet and low-vibration scroll compressors.

Question 7

What is the capacity range of the HTH line?

Accepted Answer

The HTH line ranges from 962 kcal/h (HTH 01 AR) to 63,000 kcal/h (HTH 60 AR). Smaller models (HTH 01) use hermetic compressor with R134A, while HTH 09 to HTH 60 models use Scroll compressors with R410A. Models from HTH 15 onwards have two independent refrigeration circuits for full redundancy.
