Chapter 1 Introduction
Since Vogt introduced Tube-Ice ® machines in 1938, the process of making Tube-Ice ® ice has been widely
recognized as the most economical means of ice production. These machines ’ economic and reliable operation
has been proven repeatedly in a variety of installations throughout the world. The skill in engineering and
fabrication Vogt Ice has learned in more than eight decades of experience is reflected in the HFO10 machine.
Using as little as one-third of the energy required by competing ice makers, Tube-Ice® machines produce the
same amount of ice at great savings
— in restaurants, sports arenas, packing plants, and wholesale operations
around the world.
In addition, Tube-Ice® machines are renowned for their long service life, giving many customers more than
35 years of dependable service. Ask someone who owns one.
The HFO10 machine was introduced in 2017 as the next evolution of the Tube-Ice machine. It was developed to
provide end users with a long-term synthetic refrigerant solution driven by a robust semi-hermetic screw
compressor.
Hydrofluorocarbon (HFC) refrigerants are experiencing a phase-out in a variety of markets across the globe
because of their high Global Warming Potential (GWP). This forces Original Equipment Manufacturers (OEMs) to
build forward-thinking business strategies when selecting a replacement refrigerant for use in their equipment.
The challenge with implementing synthetic refrigerants in ice machines is to find the perfect balance between
something that will work well in the application and be available for purchase for the foreseeable future. Finding
this balance has been Vogt’s focus.
V ogt’s long -term refrigerant solution is HFO (hydrofluoroolefin) blends with similar properties as R134a. These
HFO-based refrigerants have very low GWPs, which are in line with the European Union F-Gas Regulation phase-
down and with projected refrigerant regulations in the United States.
In November 2017, at the International Packaged Ice Association convention, Vogt introduced the HFO10
machine. It is the first Tube-Ice machine designed to run on an HFO blend (R513A). This blend, along with other
R134a-like HFO blends, is expected to be a long-term synthetic refrigerant solution. However, HFO blends are
likely to be replaced by pure HFO refrigerants of the R1234-family. These pure HFOs will be retrofittable to the
HFO10 machine, giving it a secure and well-defined future as the market evolves.
In addition to environmental benefits, the HFO10 machines operate at lower head pressures (approximately
130 psi or 9 bar), putting less overall stress on the system. Vogt uses
Bitzer’s innovative CSH semi -hermetic
compact screw compressor, a robust design that is more reliable than a reciprocating compressor. A further
benefit of the CSH compressor is that it produces less noise than the equivalent reciprocating design. The HFO10
has excellent energy efficiency, consuming as little as 2.68 kWh per 100 lb (45 kg) of ice produced.
The HFO10 machine is just the beginning of Vogt’s new focus to innovate and introduce superior products to the
marketplace.
