water heaters gas these digital heaters are an economical choice for generating a lot of heat raypak® commercial heaters use a patented copper tube heat exchanger for excellent thermal efficiency in some aquaculture applications copper may not be compatible requiring the use of an intermediate heat exchanger their spark ignition pilot safety controls only turn on when heat is needed these heaters have microprocessor-based thermostat controls and onboard diagnostic controls other features include stainless steel burners outdoor flue stack and rugged coated galvanized metal construction one-year warranty made in usa heaters located indoors must vent exhaust gas outdoors for indoor use add the indoor stack note standard heaters cannot be sold for use in tx or ca contact aes technical staff for low nox options compatible with those states regulations add an n to the heater part number for natural gas add a p for propane min gpm max gpm ship wt lbs temperature controller aqua logic ® digital temperature controllers can be used in a variety of applications where a device needs to be turned on/off based on temperature rise or fall a threebutton touch keypad selects °f or °c set point temperature differential and operating mode heating or cooling nema 4x rated for outdoor use temperature range for the controller is from -30 to 220°f 22 to 105°c the differential adjustment range is 1 to 30°f power cord lengths are 40 1 m each the temperature sensor probe is encased in titanium and has an 8 cable single stage controllers operate one device either a chiller 1/2 hp and smaller or a heater 1,000 watts or smaller dual stage controllers can be connected to both a chiller 1/2 hp and smaller and heater 500 watts and smaller dual stage controllers will only allow one device to be on at a time example stage 1 heating set point at 74°f with 1°f differential will have the heater come on when the temperature drops to below 73°f then turn off at 74°f one-year warranty wt volts/amps each 3 flow rate gpm heaters gas/controllers tc11 tc12 ec115r ec230r tc11s controller single stage controller dual stage controller single stage controller single stage repl sensor fits all 2 lbs 3 lbs 4 lbs 4 lbs 1 lb 115/10 115/8 115/20 230/15 125 180 195 195 56 116 162 176 176 51 gh199 gh266 gh332 gh399 is199 is266 is332 is399 199,500 btus/hr 266,000 btus/hr 332,500 btus/hr 399,000 btus/hr indoor stack for gh199 indoor stack for gh266 indoor stack for gh332 indoor stack for gh399 20 25 35 40 125 125 125 125 187 210 230 240 12 15 17 20 1,839 2,001 2,267 2,393 98 98 98 98 sensor ec115r sensor water temperature blending systems we offer compact pvc piping systems complete with temperature blending valves temperature sensors and pid controllers that will deliver from 3­35 gpm depending on water pressure dial in any temperature that is between your two or more source water temperatures and the valves will deliver water within 1ºf of the setpoint regardless of flow rate the programmable controllers can control multiple valves and can signal output to relays prices start at $1,875 without options made in usa call 541-884-0150 and ask for mike hosford or email aquaculturesolutions charter.net 40 tc11 30 20 10 0 gpm 0 10 20 30 40 50 60 pressure differential entering pressure exit pressure psi water heaters stainless steel these tankless high-efficiency 96 water-heating boilers modulate their firing rate 5 to 1 in response to the energy needs of the system in which they are installed compared to standard water heaters 82 efficiency this translates to a savings of 56,000 btus for every 400,000 btus burned for a 400,000 btus/hr unit running half the time the savings is over $2,400/yr assuming $1/therm natural gas cost so the extra cost for this higher quality heater is paid back in less than 3 years with zero clearances to combustibles and a compact lightweight design it can be installed virtually anywhere these are condensing boilers which may be vented with standard schedule 40 pvc pipe and can operate between 90 and 200ºf the heat exchanger is low-carbon 316 stainless steel asme constructed national board registered and stamped for a 125-psi maximum allowable working pressure fish water can be run directly through the heater in properly filtered freshwater systems otherwise an external heat exchanger can be used a stainless steel circulator pump and flow switch are standard equipment vwh199 vwh400 66,000­199,000 100,000­399,000 input modulation btus/hr 48,000­191,040 96,000­383,040 output modulation btus/hr supply/return connection 1 1/4 npt 2 npt gas connection 3/4 1 1/4 3 pvc sch 40 4 pvc sch 40 intake/exhaust connection 126 lbs 267 lbs ship wt 241/2 441/4 l 181/4 181/4 w 26 26 h 5,404 9,248 326 order online aquaticeco.com order by phone 877-347-4788 tech support 407-598-1401
