Gas Water Heaters How To Size: To determine the quantity of hot water requirements per hour: Figure about 2.1 parts per million Description Soft Slightly hard Moderately hard Hard Like a stone Water Softener How To Size: Determine grain hardness (3 grains acceptable without softening). Grains per gallon Parts per million Less than 1 Less than 17. Figure about 60% of the water to be hot.1 1 to 3.One grain per gallon = 17.5 17. Subtract this from the desired hot water level to arrive at the degree of rise.333 BTU/hr If heating with steam./gal) x 100 F rise / 0.3 (lb. Formula: gallons hot/hr x 8.000 grain softener Check the flow rate of softener. Determine total gallons of water to be used per hour.0 to 10. Multiply grains hardness x total gallons x hours of operation between regeneration (back washing). Example: 20 grains x 1000 gallons x 24 hours = 480. A water softener may be required if grains/gallon of hardness exceed 3 grains per gallon of water.5 gallons per pound washed. Storage capacity should equal from 1/2 to 1 hour’s demand. and make sure it is adequate.5 and over 180 and over Note .1 to 60 3.5 120 to 180 10.500 BTU/BHP. 6 . divide by 33.6 = 138.Laundry Planning Gude Water Hardness More tallow soap is required for washing in hard water than in soft water./gal) x degree rise / 0.6 = BTU/hr Example: 100 gal/hr x 8.

Example: 300 gallons / 7. feet (trough area) 40 (cubic feet required) / 1. Divide total gallons by 7.48 = 40 cubic feet of trough area Laundry Planning Gude Drain Troughs The trough depth should usually be 12 inches. and the width 14 inches. On long troughs.166 = 34. 9 . this can be decreased to 1/8” per linear foot to keep the depth from becoming too great. assume a 12 inch deep and 14 inches wide trough: 14” x 12” = 168 sq in 168/144 (one sq ft) = 1.48 gallons/cubic foot to get the total cubic feet required. In the example above.How To Size: Determine the total number of gallons to be dumped at one time by all present and future machines. Use high level rinse figures to get this total.3 feet (length of trough) Drain trough should slope 1/4” per linear foot to the outlet drain.166 sq. Extraction is carried out using either centrifugal or hydraulic extraction. . a removal of two pounds of water per pound of fabric. Clean dry weight is normally calculated by using the weight after full drying to “bone dry state”. The piston is forced towards the bulkhead. In the second type. 35 gallons (280 lb). There are two types of hydraulic extraction. a 350 lb load of cotton will hold approx.7 lb of water per pound of fabric. squeezing the water from the textiles. but centrifugal extraction is an efficient choice for certain classifications of textiles if batch cycle times allow. . the centrifugal force (G-Force) spins the water out of the fabric at high speed. polyester/cotton textiles come out drier for the same extraction effort. the fabrics are placed between a piston and a bulkhead.The extract function decreases retained moisture to a level of 50%. A 350 lb load of 100% polyester will hold approx. In the first type. Moisture retention describes the ratio of retained moisture weight to clean dry textile weight.8 lb of water per pound Therefore. moisture is usually extracted by using a hydraulic press. The extract function reduces the water content of textiles to 25% to 70% moisture retention depending on the fabric laundered and equipment used.Since 50/50 polyester/cotton retains only 1.1 gallon per pound (lb) of polyester or 0.3 gallons per pound (lb) of cotton or 2. Saturation Examples: Cotton – Approximately 0. the load has to be removed from the washer and extracted separately.5 lb of water (0. Extraction is performed in the washer-extractor. With conventional washer-extractors.3 gallons) or 250% of the dry weight. Free water will not accumulate in the cylinder until the textiles have absorbed enough water to become saturated. only 1. The process begins with textile saturation.5 lb of water per pound 100% Polyester – Approximately 0. . the pre-programmed PLC moves the washer into high-speed rotation after the laundering cycle.2 lb would be removed to reach the same 50% moisture retention. However. 10 In tunnel washing equipment. One pound of cotton textile holds 2. 105 gallons (876 lb) of water when saturated. the water is squeezed from the fabrics by utilizing fluid pressure exerted against a flexible diaphragm that houses the textiles. With centrifugal extraction.Laundry Planning Gude Water Extraction The extract function reduces moisture retention in the laundering process. The amount of water needed for saturation must be added to the amount of free water in the washing cylinders when the water consumption of laundering formulas is calculated. Moisture Retention Shown below is a Moisture Retention Chart that demonstrates moisture retention in % when subjected to differing extraction G-Forces. fabric softeners) in the sour bath.dry weight / dry weight = Moisture Retention (%) 11 ..g. however. Note that once G-Force exceeds 200G there is a diminishing return on the moisture removed from textiles compared to moisture removal from 50G to 200G. ironers.Extraction from textiles is enhanced by increasing water temperature and the incorporation of fiber lubricants (e. presses. Laundry Planning Gude There are advantages and disadvantages to each extraction method. the better the moisture removal. 140 120 Moisture Retained In % 100 80 Terry 60 100% Cotton 40 50/50 Blend 20 0 50G 100G 150G 300G 200G 250G Extraction G-Force 350G 400G Moisture retention measures the water extracted from the load. can damage fabrics. Too much water removal. the less drying time required. To calculate moisture retention. The more water removed from the load. A certain amount of water retention is required for finishing procedures. use the following formula: Weight after extraction . The warmer the fabric extracted. etc. Water removal using the extract function is more cost effective than dryers. CSL and DW models feature inverter with single motor drive. yet attain a higher G-Force than smaller diameter cylinders.Laundry Planning Gude G-Force G-Force is a relative measurement used to compare a washer’s extraction capabilities (spin cycle). larger diameter cylinders can spin slower. ESL. higher RPM’s relate to higher G-Force when the cylinder size is similar. Extract speeds are field programmable in (1) RPM increments via the DynaTrol HMi touch screen control. Comparatively. 12 . Here’s the formula to calculate G-Force: RPM2 x diameter (inches) / 70.

Thus. Dryer enclosures provide two significant benefits: The dryers will not use conditioned air from the room for make-up air. A good rule of thumb for makeup air is 1 square inch of clear opening for each 800 BTU of heat. it takes approximately 1. rear and top).500 BTU/lb to make up for any inefficiencies. If low or medium speed (80G .How To Size: Dryer should be of larger capacity than corresponding washer-extractor.200 BTU to evaporate 1 lb of water. The total emission is then 10% of the rated BTU! By enclosing the same dryer. lb) x (% water retention) x (2. always provide enough space for service at the rear of the equipment. If part of the volume of laundry is to be ironed.: a 50 lb.1. The time for drying a load can be estimated with this formula: Drying time (hrs) = (Load weight. A good rule of thumb is that a dryer will emit 2% of its rated BTU’s through each exposed face. Estimate between 1. This is especially true if the laundry will have air conditioning or some other environmental control. a dryer to washer ratio should be 2:1. so use good judgement for each situation. there are 5 faces radiating heat into the room (the front.2 . if a dryer is unexposed. Noise from the mechanical components of the dryer is also reduced by the enclosure.500 BTU/lb) (BTU per hour rating of dryer) Under ideal conditions. sides. Most importantly. Heat emission is reduced by up to 80%. When enclosing dryers. 13 . There are occasions when enclosing the dryers is not suitable. This will reduce operating expenses. a 50 lb washer would require a 100 lb dryer. since the device will restrict at least half of the opening. (i.4 and 1. Since a dryer is not 100% efficient. heat emission is reduced to only 2%. Average loads per hour: Gas fired = 2 Steam heated = 1. Thus.5 times washer-extractor capacity. always provide a properly sized make up air source. the 1. dryer capacity can be reduced.180G) are used. use 2. since the dryer is not taking cooler room air and heating it to 160 to 180 degrees. the opening should be at least doubled.4 capacity rule applies to washer-extractors with high extract speeds (G-Force greater than 200G). If a louver or screen is to be used.5 Electric heated = 1 Laundry Planning Gude Tumbler Dryers In general. dryer). It is usually best to enclose the dryers to separate the make up air supply.
