'ACE' makes
this product meeting International standards. Pharmaceutical Industries rely on ACE material for chilling purpose as well as Solvent recovery
plants.
Following grades can cover the entire range of applications of this
product.
a. FUSED LUMPS : It is available in White lumps of about 2" size with 74% min
Purity.
It is also used by cement paint
industries as well as oil drilling wells.
b. FUSED POWDER:
It is a Fine free flowing powder of 80% min Purity. it is white in colour. It has easy to dissolve property.
Hence chilling media up gradation is easy and quick with this grade. It is pure
form of Calcium Chloride. So Ca-Stearate, Palmiate, Gluconate, Citrate etc. compound
manufacturer prefer this grade from us.
c. ANHYDROUS POWDER : 99.99%
Purity, Food Grade, Mercury Free. No doubt in quality is what this product spell for
us. It is used for WATER DOSING; PHARMA FORMULATION; BULK DRUG MANUFACTURE AND
WHAT NOT ? You name the purpose; ACE can recommend it.
d. ANHYDROUS
LUMPS : 96%
min strength ISI standard, most ideal desiccant. Most reliable water separator from Solvents is
what user belives in for our product. We give M.S. or plastic or paper drum parking to
avoid powder formation of lumps. Reasonably priced is what user spells for ACE.
Client satisfaction of quality is the primary concern of ACE.
e. LIQUID BRINE : Chilling plants in large capacities cannot afford the cost of fused
grade product. Fuel being costly every
where; better to adopt chilling brine procurement directly in ready made liquid. We give 7.5
min, pH and 1.36 Sp.Gr. and Chromate addition for ready to use brine. We give below
the tips for chilling media.
TIPS FOR CHILLING
MEDIA :
A brine may be defined as a liquid
of low freezing point used in the transmission of refrigeration without
change of state. The brines commonly employed in refrigeration are
calcium and sodium chlorides. The later is cheaper but cannot
be used below its eutectic point of - 6.03 o.F. Calcium chloride
of commercial grade does not operate very satisfactorily below -40 o.F.
Although these brines
have the great advantage of low cost, they have the disadvantage of
being
extremely corrosive, and the calcium brines have the disadvantage of
throwing down insoluble
precipitates with untreated waters. Corrosion in closed systems can be
largely overcome by the
addition of sodium dichromate, Na2Cr2072H2O, 100 lb and 200 lb being
required per 1000 cu.ft. of calcium and sodium brines, respectively. Enough
caustic is added to make the brines slightly alkaline. Open calcium brine systems may be
protected by additing zinc dust at the rate of 60 lb/1000 cu.ft. a little at a time.
Other materials that
may be used are methanol, denatured alcohol, ethylene glycol and
glycerin.
These have been much used for protection of automobile radiators and are
no more corrosive than water. Their main advantage is cost, but they have been used
in place of brines for household
refrigerators. Methanol and denatured alcohol solutions are not
inflammable at refrigeration
temperatures, but at higher temperature they may give off inflammable
vapors. |
