INTRODUCTION

• On refrigerated ships (reefers), besides R22, the
  main refrigerants used are R410A, R407C and
  R404A. In 1993, five refrigerated ships using
  ammonia were built.
• Since then, ammonia has no longer been used,
  except on fishing boats.
• Indirect systems using brines such as calcium
  chloride, and plate exchangers, are the most
  commonly used.

INFORMATION

• the R-407C is a blend refrigerant of HFC32,
  HFC-125 and HFC-134a.
• It is a long life substitute of R22, harmless to
  Ozone
• It is used in various of air conditioner, and
  non-centrifugal refrigeration system.
• Retrofit of existing R-22 systems. However, 407C
  should not be used as a direct, "drop-in"
  replacement.
• Also, you should not use 407C in equipment that
  uses a flooded evaporator because of the
  zeotropic behaviour within the system.

TOXICOLOGICAL INFORMATION

• IMMEDIATE (ACUTE) EFFECTS
• HFC-32 LC50 4 hr. (rat) - 520,000 ppm / Cardiac
  Sensitization threshold (dog) 350,000 ppm
• HFC-125 LC50 4 hr. (rat) - gt 800,000 ppm /
  Cardiac Sensitization threshold (dog) 75,000 ppm
• HFC-134a LC50 4 hr. (rat) - gt 500,000 ppm /
  Cardiac Sensitization threshold (dog) gt 80,000

POTENTIAL HEALTH HAZARDS

• SKIN Irritation would result from a defeating
  action on tissue.
• EYES Liquid contact can cause severe irritation
  and frostbite.
• INHALATION R-407C is low in acute toxicity in
  animals.
• INGESTION Ingestion is unlikely because of the
  low boiling point of the material
• DELAYED EFFECTS None known.

Application

• Positive displacement equipment
• new or existing residential and commercial
  air-conditioners
• new or existing residential and commercial heat
  pumps
• conditioning applications. They include
• New residential and other unitary air
  conditioning, non-flooded evaporator chillers.
  With few modifications, 407C can be used in the
  same equipment designed for use with R-22

Suva 407C Refrigerant

• We will see now some a company cat logic which
  manufacture this type of refrigerants nowadays
  and have some real information about its
  properties, charts, curves and tables.
• We will take the Suva 407C Refrigerant
